If you were young in the ’90s and watched Nickelodeon, you’re surely familiar with Kenan & Kel. The show starred Kenan Thompson and Kel Mitchell, and ran from 1996 to 2000. Since then Thompson has gone on to a successful run on Saturday Night Live, while Mitchell has continued acting albeit in lesser known projects. Mitchell also auditioned for SNL, but it didn’t work out for him.

There have been reports of the pair not staying in touch in the years since their show ended, but last night they reunited on The Tonight Show Starring Jimmy Fallon for a sketch that re-created the duo’s 1997 movie Good Burger, which was inspired by a sketch they did on another Nickelodeon show, All That.

You can check out the Kenan & Kel reunion below, as well as a behind the scenes video and one of their sketches from the ’90s.

Andy Samberg was on The Tonight Show Starring Jimmy Fallon last night, and he and Jimmy Fallon got ridiculous as usual. Samberg has an upcoming gig hosting The 67th Primetime Emmy Awards, plus his FOX show, Brooklyn Nine-Nine (I dub it the funniest show on television), returns for its 3rd season on Sunday, September 27th. We are in for a whole lot of Andy Samberg and I am glad.

Watch those two silly videos below.

Jimmy Fallon had quite the night last night on The Tonight Show Starring Jimmy Fallon. Not only did he and Justin Timberlake do one of the show’s best bits, “History Of Rap 6,” he also accepted Ellen Degeneres‘s challenge for a “Lip Sync Battle.” This bit is so popular, it got its own show.

Watch the Lip Sync Battle below.

The cutest celebrity BFFs reunited last night on The Tonight Show Starring Jimmy Fallon – Justin Timberlake and Jimmy Fallon opened the show with their classic bit, and with help from the coolest band in the world – The Roots. JT just can’t go on the show without them breaking into song. I love it! What am I talking about? Everyone loves it! They start with “Fiesta” by R. Kelly and Jay Z, and end with “Fight For Your Right” by The Beastie Boys.

Watch The History of Rap 6 video below.

Jason Sudeikis was on The Tonight Show Starring Jimmy Fallon last night, and you know, I completely understand why Olivia Wilde fell for this guy. He and Jimmy Fallon talked for a bit about being parents, they played “Drinko,” and as a special surprise, Fallon got Sudeikis to tape a segment of his web bit, “Would You Rather?” Remember? That fun game I showed you guys last time with Simon Pegg?
