Welcome to the Good Burger, home of the Good Burger! Kenan Thompson and Kel Mitchell reunited on "The Tonight Show Starring Jimmy Fallon" and treated fans to a hilarious sketch inspired by their hit '90s Nickelodeon movie "Good Burger." The "Good Burger" reunion was the first time Mitchell and Thompson appeared on screen together since the "All That" 10th anniversary special that aired all the way back in 2005, according to Time.

Mitchell and Thompson appeared together in the mid-'90s on the popular Nickelodeon sketch comedy show "All That's." In 1997 the two made made a big-screen version of "Good Burger," their popular sketch on "All That" about two happy bumbling fast food workers.

The sketch started with Fallon reminiscing about the good old days when he worked at a "local fast food restaurant." The host then rubbed his chin and reappeared with a blond '90s-style shaggy haircut and a familiar blue-and-white-striped uniform. Mitchell did not disappoint and uttered his famous catch phrase from the film and sketch: "Welcome to Good Burger, home of the Good Burger - can I take your order?"

Halfway through the sketch, Thompson, a 12-year veteran of "Saturday Night Live," appeared as his character from "Good Burger," construction worker Lester Oaks, according to Entertainment Weekly.
