Who knew Bill Cosby was this strong?
With Jimmy Fallon taking a look at extreme sports last night, he asked The Cos to walk a tightrope across the studio. The "rope" was nothing more than a piece of tape on the floor -- but as you'll see in the video, Fallon wasn't about to make it that easy on Cosby.
As the 76-year-old comic legend teetered down the "rope," Fallon hopped up on his back and covered Cosby's eyes for the piggyback ride of his life. Somehow, he wasn't injured.
Cosby came out okay too.
