9. Behind the Music: Blue Oyster Cult
Original Airdate: April 8th, 2000
America loved it, but for new cast member Jimmy Fallon this sketch was a revelation. "I had just started on the show and I'm not the best actor in the world," he said later. "I do impressions and stuff like that. So I was stuck in a scene with the great Will Ferrell, who's one of the funniest guys ever and we do the sketch in dress rehearsal and it's OK – it's not even that great. And then, on air… he came out with a smaller shirt so that his gut would hang out when he banged the cowbell. And everyone just broke up laughing, and I couldn't stop laughing. That's what you get when you play with the big boys." Though, yes, you got sick of the catch phrase, and the T-shirts and maybe even the whole idea of cowbells – and cows and bells. But the majesty of this lovingly ironic Seventies rock parody is pretty undeniable.
