Comedy at Comic-Con 2010 (VIDEO)

Comedians seemed to take over this year's Comic-Con in San Diego. Here are some video highlights from the geekiest weekend of the year.

Will Ferrell and Tina Fey (along with Jonah Hill) made an early appearance to promote their new animated film Megamind. Ferrell gamely appeared in full costume, which was clearly made just for Comic-Con. And Tina Fey revealed that her nemesis is Betty White.

For the Scott Pilgrim vs. the World panel, director Edgar Wright presented Michael Cera, who dressed as Captain America. Cera told the crowd that he felt it was "predictable" that he was not cast as that role.

The full cast of Community (hot off of egregiously not being nominated for any Emmy awards) sat for a panel that included the public debut of Donald Glover's dirty homeless man character and an always appreciated Abed and Troy rap.

Adult Swim's Children"s Hospital had its coming out party at Comic-Con, graduating from web series to actual TV series, and the large and talented cast was on hand to make jokes about it. If you were wondering if they are fans of actual medical dramas, the answer is no.

And finally, in this clip, the cast of It"s Always Sunny in Philadelphia took the stage to discuss the upcoming season. These guys all seem to be dressed as themselves, but were no less funny answering audience questions and singing a bit of "Day Man."
