Friday, May 9th

Will Blair get Her bitchgroove back? This and other pressing matters will be up for discussion at “Ultimate Gossip Girl Summit at the People’s Improv Theater, sure to warm the cockles of Serena van der Woodsen’s heart. (Note to self: Maybe we should cut our hair like that?) Other topics on the tableau include “Will the black girl ever get a speaking role?”;What happened to the Asian girl?”; and “Who is Georgina?” In other comedic news, naughty Sarah Silverman appears in the flesh at Columbia University to perform a benefit show for Project A.L.S. “Project A.L.S. is a vital crusade—to find a cure for a horrific disease—and also to fight for the legality of stem cell research—for the right to put science over fundamentalism so that people may live past this and countless other diseases,” wrote the suddenly sérieuse comedienne in an e-mail that was far tamer than the material she’ll be trying out onstage.
