I've long suspected that what goes on during the commercial breaks of late night shows is funnier and better than the show itself. This video seems to be proof of my theory.
When Jerry Seinfeld was on "Late Night with Jimmy Fallon" Tuesday night, the comic and the host took some time during the commercial break to take audience questions. Seinfeld naturally ripped apart any queries that came his way, going on a riff at one point about the short attention span of a guy who asked "When's your next show?" The video really gets good toward the end when Fallon has to tape promos, only to keep getting critiqued by Seinfeld. He can't keep a straight face (although this certainly isn't a new problem for the SNL grad).
