Billy Crystal was brilliant here. Jimmy Fallon was awesome too. This was incredibly funny.

You have very 'expressive' eyes Jimmy! Made it even funnier

DO NOT watch this after your roommate's gone to sleep, I feel like my entire body is in one giant cramp from laughing so hard and trying not to laugh out loud [passes out]

Leave it to jimmy to always put a smile on my face

[TheKittty]

U truly brighten up my day. Tired, lonely, had a seizure. All depressing. But YOU r just what I needed

[TokyoKazama]

It would've been funny if Jimmy as Billy, said that he had brought a copy of a book for all the audience members (assuming it had not been arranged beforehand).
