Super special guests Billy Crystal and Jerry Seinfeld helped Jimmy Fallon to do an updated version of Abbott and Costello’s classic “Who’s on First?” bit last night on Late Night, with a couple of awesome performances from less-famous people Steve Higgins and A.D. Miles. Sorry, Steve Higgins and A.D. Miles for not including your names in the headline of this post! You don’t quite have the name recognition of Jerry Seinfeld or Billy Crystal and you appearing on Late Night is far less of a big deal.
