Watch Jimmy Fallon Impersonate Bill Cosby To His Face... And Dance Behind His Back

It's one thing to do a funny celebrity impersonation. It's another to do that impersonation to that celebrity's face. Jimmy Fallon is mastering that art on The Tonight Show Starring Jimmy Fallon, having previously engaged in a bit of impression-riffing with Jerry Seinfeld, and more recently showing off his Cosby impersonation to comedy legend Bill Cosby himself.

Ok, we're going under the impression that Mr. Cosby's being funny with his cut-it gestures...

And hilariously unimpressed expression...

...because his reactions are even funnier than Fallon's impersonations, I'd say.

As mentioned, Fallon had us in hysterics when he and Jerry Seinfeld engaged in a bit of impromptu impression riffing during Seinfeld's interview.



Fallon can dish it out, but can he take it? Damn right he can, though not entirely with a straight face. Watch him go face to face with Justin Timberlake in this recent Saturday Night Live episode in which Fallon impersonates Jim Parsons and Justin Timberlake impersonates Jimmy Fallon...



And if you can't get enough of Fallon's celebrity impressions, here's a video of Fallon demonstrating more of them on an episode of America's Got Talent:
