With its emphasis on music and games over tedious, pre-scripted interviews, "Late Night with Jimmy Fallon" is in many ways the freshest show of the late-night genre.
But on Thursday night Fallon and a gang of fellow funnymen, including Billy Crystal and surprise guest Jerry Seinfeld, served up a new version of the classic Abbott & Costello routine "Who's on First?" about a team of peculiarly named baseball players.
When it comes to comedy, it doesn't get much more old-fashioned than "Who's on First?" Despite being a total throwback -- complete with vintage uniforms and a Vaudeville set -- the bit felt every bit as exciting and new as, say, the latest round of "Water Wars."
