About a week ago, we were speculating on the question of whether Charlie Sheen's legal troubles would impact on 'Two and a Half Men's' future. Today, it was Charlie Sheen's personal problems that resulted in the show shutting down temporarily. Charlie Sheen has checked into rehab as a precautionary measure.

It's hard to see this as a precaution because for weeks now, Sheen's life has been spiraling out of control. The Aspen situation with wife Brooke Mueller, the felony charges and a relapse into substance abuse of some kind are all proof that, for now, Sheen is not able to continue with 'Two and a Half Men.'

According to The Wrap, shuttering 'Two and a Half Men' for some time could be a problem for CBS. The Monday night schedule hinges on 'Two and a Half Men,' and prolonged reruns when new episodes are airing all around the nine o'clock time slot could drag down the Nielsen numbers. Although considering how strong CBS remains on Monday, it would take more than some reruns to cripple CBS's comedy juggernaut.

(S03E04) Do you have the nerve? That was the question a few times this go-round. If you get off on the "I double dog dare you" kind of action, then you were right at home. Chuck was put in an impossibly emotional situation, a continuation of last week, with Awesome drawn into Chuck's web of espionage. Would he be able to keep it together and use the Intersect to help his bro-in-law? And what about the new guy in the mix, the off-camera character the General was talking to? All that and more after the jump.

(S07E11) How great is it that Jake Harper has turned into a rotten teenager? No more the butt of the joke (okay, he still is on many occasions), now at least he's dishing it out as well as getting it. This was one of the better shows of the season and I think it's because they shipped Chelsea out early on. Can she stay away permanently? More on that and the mice at play after the jump.

Good news for Patrick Warburton fans; disappointing news for Jenna Elfman fans. And if you have a deep affection for Jeremy Northam, this should make you happy, too. Confused? Don't be. I'm just laying out the essence of the CBS midseason juggle.

On Mondays, beginning February 1, Accidentally on Purpose will be shelved... but only for a few weeks. Taking the 8:30 Monday slot will be the return of Patrick Warburton, the best thing in Rules of Engagement.

That's not all. On March 31, the 8:30 slot in which Gary Unmarried airs, will be assumed by Accidentally. That's not because Gary's being canceled; it will have completed its season order by then.

So last night I sat down for some laughs with the CBS Monday night sitcom lineup. It's a weekly thing I do with my spouse, a chance to get away from the computer screen and just relax for a while. Normally, I relish this time because -- for the most part -- I love 75% of the shows from eight o'clock till CSI: Miami. (I usually empty the dishwasher during Accidentally on Purpose, sort of half-watching it because, as I've said before, it's just not working for me.)

Well, it seemed like last night's CBS comedies went off the rails. They strained to be funny, in all the wrong ways. Here are my thoughts, show by show -- including Accidentally (which I did watch):

How happy is Chuck Lorre this morning? I'd say on a scale of one-to-ten, he's an eleven. According to reports, CBS wants more of its Chuck Lorre sitcoms. In particular, they're talking three years more of Two and a Half Men and at least two for The Big Bang Theory.

While other shows sweat out the word of renewal or cancellation, Mr. Lorre seems to be CBS's prime time player they count on the most. Okay, second-most. Jerry Bruckheimer is numero uno with the CSI franchises, Without A Trace, Cold Case, Eleventh Hour and The Amazing Race.

Here at TV Squad, we often bemoan the quick cancellation of a show that deserves a chance to evolve. We've chronicled the demise of a fan favorite like Moonlight, and empathized with our readers. There have been times when we've agreed that networks spend so much time and talent developing a show that it seems a down-right shame when the plug is pulled after a half-dozen episodes.

So, knowing all that, we have to acknowledge when a network does something right. NBC is bending over backwards to see to it that Chuck becomes a ratings hit, to go along with its already established and growing fan base. Creator Josh Schwartz expressed his thanks to NBC for the post- Super Bowl Chuck episode. The Super Bowl is Sunday, February 1.

"They were doing this big promotion inside of the Super Bowl and handing out 150 million 3-D glasses, so we are the beneficiaries of that. ...Chuck seemed like the best fit for that type of thing."

I can't say I've been thrilled with some of the announced pick ups for the remainder of the season. NBC's faith in Knight Rider, for instance, has me scratching my head. Here's one that I can get behind: ABC has given Samantha Who a full season pick up.

The Christina Applegate single camera comedy -- which includes Jean Smart's Emmy-winning supporting performance as Sam's alternately attentive and annoying mother -- has had a terrific sophomore season thus far.

I'm not talking about the ratings, although ABC is pleased that the show has been doing a good job holding onto the strong lead-in from Dancing With the Stars (although this is not a scintillating edition of Dancing). For me, Samantha Who is just as funny as last year, but now things are getting more complicated and interesting.

Just last week, for instance, Sam was given an experimental drug to -- hopefully -- help her reclaim lost memories. Through flashback flashes we learned a lot more about Todd and Sam's relationship and how they've gotten to where they are. The episode was packed with emotion and funny bits of business, and yet in the end we were still on that precipice, waiting for Sam to remember that she loves Todd.

CBS has a killer Monday night lineup. The sitcom block from 8 p.m. to 10 p.m., followed by the very popular CSI: Miami consistently delivers in the Nielsens. The only vulnerable, flexible and soft spot is 9:30, after Two and a Half Men, before Horatio Cane and company.

The network apparently isn't sure that Worst Week has earned that coveted spot -- even though it's doing well enough in the ratings -- or else they're wondering what they have in Gary Unmarried.

Next Monday, Gary Unmarried will get a shot at 9:30. The pilot episode of Gary Unmarried -- which was pretty good -- will be rerun in that cushy timeslot with the idea of getting more people to sample it.

The new TV season has produced at least one breakout star for sure -- Kyle Bornheimer. On Worst Week, CBS's new entry in its solid sitcom block on Monday nights, Bornheimer has made his mark and the show is proving a ratings hit.

Kyle's every guy, not too bright, essentially sweet character on Worst Week, Sam Briggs, fits him like a glove. It's his ability to deliver the physical comedy as well as the self-deprecating lines with a knowing smile that has made him endearing.

Kyle Bornheimer has one of those really recognizable faces. You might remember having seen him in Jericho or Breaking Bad or The Unit. He's been kicking around for the past few years, searching for a role that would give him a chance to shine. That's what he's found in Worst Week.

Earlier today, Anna reported that the leaders of Writers Guild of America were to decide when to begin their strike against the studios and networks. Well, that decision has been made, and, as many speculated, the writers will definitely walk out on Monday.

As you might expect, the impact of the strike will be seen immediately on the late night talk shows. Jon Stewart mentioned on last night's The Daily Show that he didn't think there was going to be a new episode on Monday because of the strike and he was right; since there is no backlog on those late-night shows, they'll all be in reruns starting on Monday. Hopefully the strike won't drag on to the point where we run out of new episodes of scripted shows, but this matter of revenues from alternative delivery methods (DVDs, online, iTunes, etc.) is a sticky one that's not going to be settled easily. How long do you think the strike is going to last? Let me know in the comments.

Hey, folks. I'm in Pasadena, at the Television Critics Association winter press tour. Thanks to Kevin Kelly for doing Friday's session as I was flying in from New Jersey. After a night's sleep and a tour of "beautiful" Hollywood (including a stop at legendary hot dog haven Pink's, where I waited for an hour in 45 degree cold to get a chili dog. Yes, I'm one of those guys), I'm refreshed and ready to go.

Anyway, today was the first of the broadcast network presentations, and we started with an announcement: the new season of Dancing with the Stars will be start on Monday, March 19th. Why Monday instead of the previous season's Tuesday timeslot? Two words, according to network president Steve McPherson: American Idol.

The Hollywood Reporter is claiming that NBC execs plan to move Friday Night Lights to Sunday nights once the NFL season is over. The move is a strategic one-- to keep FNL out of the line of fire of Fox's unstoppable American Idol, which begins airing on Tuesday nights in mid-January. Last week, NBC ordered up a full season of FNL, which gets an average of 6.7 million viewers each Tuesday night.

This schedule change is reportedly one of many, as the New York Times and The Hollywood Reporter now both say that NBC is planning a major schedule overhaul for January (NYT says the new schedule will be announced this week). Also slated to move is Studio 60 on the Sunset Strip, which currently festers at 10 pm on Monday nights.

In a move that's a bit of a head scratcher, The CW has decided to flip-flop its Sunday and Monday night schedules. That means the oddly paired 7th Heaven and Runaway will be on Sundays, while Everybody Hates Chris, All of Us, Girlfriends and The Game will move to Monday nights. The switcharoo puts The CW's comedy block up against CBS' Monday night comedy block, which includes How I Met Your Mother and The New Adventures of Old Christine. The schedule change begins Monday, Oct. 9 for the comedies and Sunday, Oct. 15th for the dramas.

President Bush has asked the networks for some time on Monday night at 8pm for his immigration speech, so the networks are going to have to change things around a bit.

• NBC will shorten Deal Or No Deal to 90 minutes.
• FOX will show all of Prison Break and 24 after Bush's speech.

ABC (Oprah's Legend's Ball special and the Grey's Anatomy season finale) and CBS (comedy lineup and CSI: Miami) won't announce their plans until Monday.
