Watch Jimmy Fallon and Fred Armisen Be The Beatles On "The Tonight Show"

Last night Jimmy Fallon had his old bud Fred Armisen stop by The Tonight Show Starring Jimmy Fallon to talk about his new gig as the bandleader on Late Night With Seth Meyers.

Before the two began to chat, they went back in time and and became members of The Beatles, chatting it up with a nearly rabid audience after their famed February 9, 1964 performance on The Ed Sullivan Show. This is certainly not that. It's Fred Armisen and Jimmy Fallon reliving their days as Saturday Night Live cast-members going deep into character and asking the audience to do some strange things, considering the video is supposed to transpire 50 years ago.
