How well do you know the show?

Since premiering in 1994, 'ER' has seen a lot of action -- and quite a few cast changes. George Clooney, Anthony Edwards, Julianna Margulies, John Stamos and many others have walked the halls of County General.

After 15 seasons of ups and downs, it's time to test your 'ER' knowledge by taking our quiz.

I have come to an epiphany when it comes to American Dad and Family Guy: a studio audience is needed. I came to this realization after attending both the Comic-Con panels for these respective shows, which showed clips from their respective series. Scenes that I would have generally smirked at or given a chuckle made me laugh out loud along with the rest of the audience. Which brings me to one of two conclusions: either laughter is contagious, or I am just a lemming.

Either way, an enjoyable two hours was spent with casts from both shows as they did some table readings, provided some clues to upcoming episodes,and provided clips from some previously run and new episodes of both shows.

Casting news from ER: Stanley Tucci, star of the very short-lived CBS drama 3 Lbs last year, will join the show later this year for a multi-episode stint.

He's going to play "a brilliant ICU turned ER chief," in just one of many big changes that are coming to the show. TV Guide wonders if this means that Goran Visnjic will be replaced, since it has been reported that Visnjic might not return next season (though producers are trying to get him to agree to star in a few episodes here and there).

This is interesting casting, going for an older guy instead of a resident hunk (sorry, nothing against Tucci's hunkiness). This guy deserves a weekly show. I remember a TV movie from years ago, a pilot for a series produced by Tom Selleck, that had Tucci as a detective. The show never made it, so I hope this works out.

(S13E11) McCreamy. Yes, in a, um, subtle jab to another popular medical drama on an opposing network, Neela is introduced to a doctor who has a certain addiction to, well, spanking his monkey (that's the medical term, of course). The interns in the surgical department have nicknamed him McCreamy. He tries to shake Neela's hand after she finds out about his secret, but she makes a hasty getaway.

Okay, that wasn't the main plot of this week's episode, but I wanted to mention it first just so I wouldn't forget it. No, this week was the annual Christmas episode. And, like past seasons, this episode featured hope, good cheer, and some misty eye moments. That, and it was pretty much Abby and Luka free. We only saw them three times this episode. We also learned that Curtis Ames had filed a restraining order against Luka after the good doctor threatened to kill the stroke victim in last week's airing. Luka, Luka, Luka, won't you ever learn?

(S13E07) Hey there! Before I begin I want to thank Jen Creer for filling in for me last week while I was out. You da, er, woman, Jen! And now, let's begin.

I'm not a big fan of the 'one patient' episodes that ER gives us a few times each season. Personally, I love the breakneck pace of seeing a number of patients that the show has been famous for. But, this time it was different. Most likely because it was the doctor who was treating the patient . . . Archie Morris. After wishing for a focus piece on our selfish, red-headed doctor after seeing him at work in the season premiere we finally got one this week.

Scott Grimes is actually one of the few famous people I can say I knew somewhat well at one time. Back sometime around 5th grade or so, Scott was in my class in a small grammar school in Dracut, Massachusetts. I remember his first forays into the acting world, as he sang and performed well beyond a young kid's talents in school plays, then public television talent shows and eventually commercials. I remember at one point, he'd gotten a gig with a popular (at the time) toy car company, and how jealous we were that they gave him a bunch of the cars for doing the commercial. Times sure have changed for Mr. Grimes since those days.
