Jimmy Fallon keeps facilitating the '90s TV show reunions of our dreams, and this week, he hit one of the best Nickelodeon sketches-turned-movies: Good Burger. Kel Mitchell and Kenan Thompson reunited for the skit, in which Jimmy flashes back to his first job — at Good Burger, of course. It's as silly as anything that came out of the All That days, but obviously, it's just amazing to see Kenan and Kel together again!
