This means war ... water war, that is!
Jake Gyllenhaal stopped by "The Tonight Show" on Wednesday to promote his new movie, "Nightcrawler," and he got roped into a rousing game of Water War with Jimmy Fallon.
Sitting across from one another, Jake and Jimmy got chances to splash each other based on the draw of a card.
"We're playing the card game war but if you lose the hand, you get a pint of water in the face," the late night host said. "We each have five glasses of water; the first one to throw all five glasses on their opponent wins, and then gets to water cannon the loser."
The actor was hesitant about the game at first, but he really got into it!
"This game is totally fixed!" he yelled after a particularly large dunking. But, he ended up getting his revenge on the comedian when he lifted Fallon's jacket to pour a full glass down his back.
Spoiler alert: both men get soaked, and Jake looks pretty great in a wet shirt!
