Who's On First with Billy Crystal and Jimmy Fallon

Bill Crystal's 1986 HBO Special, "Don't Get Me Started," featured the comedian playing many of his best SNL characters, and had numerous guests: Rob Reiner, Eugene Levy, Brother Theodore and Christopher Guest among them.  Here's most of them, along with "Sammy Davis Jr." in my favorite, hilarious scene.

And as a bonus, here's Crystal 26 years later, with Jimmy Fallon and Jerry Seinfeld, doing the same routine.  If memory serves, these are #SNL4kidz safe, but please double-check.
