Video: Kelly Clarkson and Jimmy Fallon Master the History of Duets

Move over, Justin Timberlake. Jimmy Fallon has a new musical partner-in-crime.

Having already mastered the history of rap, the Tonight Show host tackled his next feat: a history of duets with America’s first Idol, Kelly Clarkson.

The duo sang their hearts out – and tickled many funny bones – on such beloved numbers as Sonny & Cher’s “I Got You Babe” (complete with hair-flips), Dolly Parton and Kenny Rogers’ “Islands in the Stream” and Linda Ronstadt and Aaron Neville’s “Don’t Know Much.” Dumb and Dumber fans, meanwhile, will particularly appreciate a certain avian-related ditty.

So hit the PLAY button above, and try not to sing-along at home. Really, go ahead and try. We dare you!
