Propofol was the powerful drug that was administered to Michael Jackson before his death, and helped lead to the manslaughter charge against his doctor, Conrad Murray. On 'The Graham Norton Show' (Sat., 10PM ET on BBC America), Robin Williams talked about the power of the drug and his own experiences with it.

Put quite simply, Williams was on Propofol during heart surgery, giving a pretty clear indication of its strength. "It's a devastatingly powerful drug that has to be administered in a hospital situation, and he was doing it at home," Williams said of Jackson.

He talked about waking up from the surgery, disoriented from the drug. He'd received his surgery in Cleveland, and yet when he was told where he was, his first question was, "Why?"

It's always entertaining when Robin Williams is doing his thing on a late night talk show, but there was perhaps no one more entertained than host Craig Ferguson on 'The Late Late Show' (Weeknights, 12:37AM ET on CBS). Ferguson was telling a story about a sign he saw in a Scottish bar warning people about chlamydia.

At this, Williams erupted from his seat and shouted in a thick Scottish accent, "Chlamydia, your dad's here! He parked the van out back."

That was all it took for Ferguson to completely lose his composure. He so couldn't believe what he'd just heard that he had to confirm Williams said what he thought. "That's the stupidest thing I ever heard," he laughed. Stupid funny, perhaps, based on that reaction.

Robin Williams and Craig Ferguson both know a thing or two about offending people. In this modern era of instant Internet feedback, it seems it's getting harder and harder to not offend people. Which is why, according to Ferguson 'The Late Late Show' (Weeknights, 12:37AM ET on CBS), you stick with Nazi jokes.

Williams modified that claim, though, with one caveat. It doesn't work if you're in Germany, as he found out first-hand. On a talk show, he was asked why he thought there aren't as many comedians in Germany.

"Did you ever think you tried to kill all the funny people?" he replied. The answer was not received with laughter.

More cow valve! When 'The Daily Show' (weeknights, 11PM ET on COM) host Jon Stewart asked Robin Williams how his post-surgery heart was doing, the actor didn't mince words.

Always quick with a routine, this one a Christopher Walken impression, "More cow valve," Williams painted a not so lovely image.

"The wonderful thing about a cow valve is you can [bleep] standing up," Williams said, causing Stewart to double over in laughter -- or horror.

"I did not need that image," Stewart said. Us too Jon, us too.

Last night on 'The Tonight Show,' Robin Williams serenaded Conan O'Brien with a profanity-filled Irish jig expressing a none-too complimentary opinion of NBC and its executives.

Williams appeared on the penultimate 'Tonight Show' featuring O'Brien as host and belted out the dirty ditty, which came complete with rude hand gestures and Irish step dance.

First she did a twirly hug, then made an odd, slurry joke about a kitten, spoke at a rate of about one word per minute and seemed to have her own personal hype man ('Precious' director Lee Daniels). And what did we do while we watched Mariah Carey's acceptance speech for Breakthrough Actress at last weekend's Palm Springs Film Festival?

We winced. We cringed. Then we watched it again.

Carey's, uh, loosened speech was the first genuinely awkward moment this award show season, but there were many actors, filmmakers, and musicians before her who've heard their name called, stepped to the podium, and made things a little weird for everyone.

Leno's had a couple of nights now to get a feel for what kind of show he wants to do, and figure out how to stay relevant in prime time. Most of the feedback that I've seen from people who saw it hasn't been very positive. They're disappointed that it feels so much like The Tonight Show.

If one of the ways he's trying to differentiate himself is by having longer comedy bits and fewer guests, then I think that's backfiring a bit because every single comedy video he's shown has gone on way, way too long. It's as if they're trying to create internet viral-worthy videos like Saturday Night Live has with their "Digital Shorts," but they're missing the mark.

Anyone who's interested in the Leno/Letterman relationship, the feeding frenzy in the late 70s and early 80s when networks were sweeping up stand-up comedians and changing their lives overnight, and the importance and mechanics of getting a spot on Johnny Carson's Tonight Show needs to read William Knoedelseder's new book, I'm Dying Up Here: Heartbreak and High Times in Stand-Up Comedy's Golden Era.

The centerpiece of the book is the labor discontent between comedians and the Comedy Store that kicked up in 1979, when comedians saw the money coming into the venue and started to wonder why some of the working comics there had to borrow money for breakfast. It's a compelling and unexpected story, and it collects names big and small from television history along the way.

According to the UK Telegraph (and I always have trouble believing anything from the British media, but bear with me), none other than Robin Williams has offered himself up to play Susan Boyle in any planned movie of her life. Apparently, he's been doing impressions of the breakout singer for celebrity friends.

This could very well lead to Robin's second Oscar (his first for a non-supporting role). If he pulls this off, he could be as impressive as Meryl Streep playing Julia Child. Of course, if he can't pull it off, it would look like a sad attempt at repeating Mrs. Doubtfire.

However, unless they start work on the movie tomorrow, this will likely be chalked up as an interesting and amusing rumor. While her story is interesting, Susan Boyle's star has been dimming somewhat and it wouldn't surprise me if she was relegated to Celebrity Big Brother in the near future.

I wanted to write about this panel last night. However, the cumulative effects of my afternoon sojourn to In-n-Out Burger to have a double-double and fries, both "animal style," and the evening Food Network party that included a roasted pig, gourmet grilled cheese and other chef-created delicacies, caused me to collapse into a food coma at around 11 PM.

But l couldn't let two of HBO's panels go without comment. One was for the new comedy Bored to Death, based on the writings of Jonathan Ames. Joining Ames on the panel were Jason Schwartzman (via satellite), Ted Danson, and the hot comedian of the moment, Zach Galifianakis. The other was Robin Williams, who was promoting his new HBO special, Robin Williams: Weapons of Self-Destruction, which is set to air in December.

It wasn't surprising that Galifianakis' weird sense of humor dominated his panel; anyone who's seen him on the Comedians of Comedy tour or in The Hangover would have expected that. The surprise was that, in his panel, Williams was more reflective and pensive than manic.

It's always great to see Don Rickles on TV. He's rarely out of form, and he has a knack for sailing some great zingers past the censors. Which means his appearance on last night's My Life on the D-List was a perfect opportunity, a place where he could be a bit more loose.

We got a taste of that from him, walking around Kathy Griffin's house, but we also got a glimpse of the guy I have heard about from comedians who've met Rickles - the old softie who is ever willing to talk shop with other comics. It was a great moment when Griffin and Rickles talked about how both of their mothers would try to tell them not to pick on people so much, with Griffin's mom providing a bit of the dialogue. Meeting Rickles was on Griffin's mother's "bucket list."

I thought I'd use the occasion to take a look around YouTube to find some of Rickles' best TV appearances. He seems to have been everywhere, from The View to cable.

When Law & Order: SVU returns on September 23, it's bringing a trio of guest stars with it. Luke Perry (90210), Sara Gilbert (Roseanne, 24), and Julie Bowen (Ed, Lost) are all set to make appearances. Perry and Bowen play a couple accused of abusing their foster child. Gilbert is on board to play the child's biological mother.

In addition to the main foster-child abuse storyline, the premiere is going to deal with Benson's (Mariska Hartigay) attempted rape a the end of last season, as well as Fin's (Ice-T) possible transfer out of SVU. The premiere also marks the debut of the new ADA played by Michaela McManus (One Tree Hill).

Television has often been a benchmark of current popular culture. Whether it's clothes, cars or furniture, people have always looked to TV to help them decide how to look and how to live. Here are ten great examples of how TV characters have "helped" us look our best.

Daisy Duke's Daisy Dukes (The Dukes of Hazzard)
No one knew it at the time, but when Catherine Bach slipped on those ultra-short denims, she was making an impression on more than the teenage boys who were watching. Years later, a brand new and very different generation embraced the Daisy Dukes, much to the delight of those teenage boys who were now old enough to know better.

As AOL Television continues their look at the 50 Best TV Comedies -- Ever with their Top 10, we here at TV Squad are also looking at television comedy, but with a slightly skewed difference. Last week, we took a look at the Saturday Night Live cast members from 1996 to 2006 that made it to the big time. This week, we get a bit more serious.

There are those in the industry who say that it is easier to go from acting in a drama to acting in a comedy than it is the other way around. Yet, as you will see from the list we've compiled after the jump, there are plenty of comedic actors who have jumped from the world of comedy films, stand-up comedy, and television sitcoms into the more serious world of drama. In many cases they have had even greater success than they did on the other side of the tracks. There have even been instances where they stayed in the drama genre and never went back to being funny.
