Kenan Thompson and Kel Mitchell had an awesome reunion back on the Good Burger set, on The Tonight Show on Wednesday, Sept. 23, with a little help from Jimmy Fallon.

Continuing his mission to bring our fave shows back to life (Fallon was to thank for last year's iconic Saved by the Bell and Full House reunions), the show host set the scene by telling audience members about one of his first ever jobs.

"Back in the '90s I worked in a fast-food restaurant," Fallon divulged. "I remember it like it was yesterday."

As the screen wobbled into Fallon's memory sequence, the talk show host was joined by Mitchell -- there to promote his new show Game Shakers -- in the Good Burger store, first made famous by the pair's comedy sketch on the Nickelodeon series All That, and which later went on to become a movie of its own in 1997.

Mitchell played the role of Ed, manager of Good Burger, while Fallon was his staff member. But halfway through the sketch, the reunion became complete when Thompson walked into the store, playing the role of a construction worker after some fast food, and not in the mood for Mitchell's frivolity!

The crowd went wild as the 37-year-old actor jumped across the counter to give Thompson, 37, the "good shake" he'd asked for, and then reached new levels of insanity when Mitchell, and later Fallon, 41, decided they must be brothers — and not only that, but Thompson must be their dad!

 Watch the whole epic reunion in the video above, and don't miss the "Spicy Chicken Rap!"
