Ladies and gentlemen, your new favorite party game. Mark Ruffalo and Stephen Merchant stopped by The Tonight Show on Thursday, Nov. 20, and were promptly challenged to a round of Musical Beers by host Jimmy Fallon.

"The game works like musical chairs, but instead of diving into empty chairs, we're grabbing these red cups of beer," Fallon explained to his guests, who were joined by Steve Higgins and The Roots' Tariq.

"While the music's playing, we'll walk in a circle around the table; when the music stops, everyone has to grab a cup," he continued. "After each round, there will be one person left empty-handed."

With Questlove in the DJ booth, the five contestants proceeded to circle the table, hilariously trying to anticipate the end of the music. When it finally stopped, there was a mad rush for the cups of beer, resulting in some very messy fun.

"I'm a little competitive," Fallon joked after one particularly wet round.
