While the fashion flock shopped at the 69th Regiment Armory's Seventh on Sale spectacular on Thursday night, the funniest faces of television comedy gathered 52 blocks uptown at the American Museum of Natural History's annual fundraising gala. Filtering through the Hall of Biodiversity and into the Hall of Ocean Life for a 500-person sit-down dinner were late night's Conan O'Brien and a sizable Saturday Night Live contingent: Seth Meyers, Horatio Sanz, Andy Samberg, and Amy Poehler, the last of whom spent most of the cocktail hour draped on 30 Rock's Alec Baldwin. "No funny business," she assured passersby, however. "It's just friendly here." During dinner, she took her act to the stage, where she performed alongside her Weekend Update co-host Meyers. Afterward, Tom Petty and the Heartbreakers played a set for an appreciative crowd that included Tom Brokaw, Brian Williams, Harvey Weinstein, and Caroline Kennedy Schlossberg.
