As the revered tradition of Oh, Hello dictates, Nick Kroll and John Mulaney — excuse us, Gil Faizon and George St. Geegland — invite a well-known person to join them onstage about halfway through the show to participate in a fake TV segment called “Too Much Tuna.†Most recently, the cranky septuagenarians recruited “rising star in the world of entertainment†Seth Rogen for the honor, and the group discussed everything from Jewish summer camp to popular movies Jewish to the art of Jewish humor. Too bad we’ll probably never see Shlomo Gump come to fruition. Life is like a box of rugelach, baby.
