At least for this decade.
Personally, I don't have any use for Jimmy Fallon. I don't think he's funny. He's not even mildly amusing. He always seemed the perfect example of the complete de-evolution of SNL. If Dana Carvey was a shitty substitute for Chevy Chase, Jimmy Fallon was an even shittier substitute for Carvey (and Carvey is a complete douche).
But, I have to say -- this is genius:
His Neil Young impersonation is spot-on. And yes, that is the real Bruce Springsteen (in makeup) accompanying the untalented (or so I thought) Jimmy Fallon.
