Even Sherlock may need some help with this one.
On Monday, Jimmy Fallon played a new game called Three-Word Stories with Benedict Cumberbatch. In the game, Fallon and Cumberbatch take turns telling stories three words at a time, trying to get each other to guess a mystery word.
The pair started out strong, with Fallon getting the "Imitation Game" actor to guess "unicorn" correctly, but everything fell a part when Cumberbatch tried to make Fallon say "booty." Though it was a pretty hilarious struggle, Cumberbatch can take comfort in the fact that at least no one asked him to say "penguin" for once.
"The Tonight Show Starring Jimmy Fallon" airs weeknights at 11:35 p.m. ET on NBC.
