90s sitcom duo Kenan Thompson and Kel Mitchell reunited on The Tonight Show Wednesday and joined Jimmy Fallon in a #TBT-worthy trip to Good Burger.

The Good Burger sketch originated on the Nickelodeon Series All That, and if you're a fan of that great '90s Nick programming, prepare yourself for a huge dose of nostalgia.

Over the years there has been speculation that Kenan and Kel weren't on speaking terms, alluding to a fallout, as Kenan worked at his solo career.

Check out how they worked Kimmel into the skit.
