The entire episode is worth catching, but a few highlights include Fallon in a local production of War Horse, playing the war horse, and a Weekend Update Joke-off with former co-anchors Fallon and Fey facing off against another team from the past, Seth Myers and Amy Poehler.
The SNL website also posted a very prescient video from Fallon's cast-member days, a Christmas opening monologe with Alec Baldwin. Fallon appears as the Ghost of Hosts Future, promising he'll have his own show and come back to host SNL on Dec. 12, 2011. I guess no one bothered to look at a calander back then, but Lorne Michaels does have a way of making those wishes come true.
