Watch Benedict Cumberbatch And Jimmy Fallon Play 'Mad Lib Theater' On The Tonight Show

Oh, crumbs! (Wait, this is Benedict Cumberbatch, not Hugh Grant.)

Benedict Cumberbatch might have a hard time thinking up words that don't somehow relate to sex. But at the same time, everyone know that the "dirty" words are what make Mad Libs way more fun. On The Tonight Show, Jimmy Fallon asks him for nouns, movie quotes, body parts and the like. Then, the two of them take their creation to the stage.
