Spin it, DJ Richie "The Big Bopper" Belding!
It must be great being the host of The Tonight Show and able to just casually insert yourself into all your favorite childhood memories. Even some of the original cast members couldn't get it together for this reunion, but Jimmy Fallon gets a whole character arc. He even rewrites his own history and plans to finally go on that date with Nicole Kidman.
This video is probably three times longer than the written sketch due to the wild cheering of the crowd, but if you were a fan of the show you'll be cheering inside, too. Or sitting in stunned silence when you realize Elizabeth Berkley is 42.
