This is a version of war we've never seen before!
On Thursday, Ryan Reynolds stopped by the "Late Night with Jimmy Fallon" show where things got a little heated ... and wet.
Ryan and Jimmy Fallon played a card game of "War," except each time they draw cards of equal value the guys go to "War"... with water. Check out the hilarious clip above to see what Reynolds said about Jimmy's nipples.
That's one way to beat the heat!
After going through several cups of water, Fallon took the win and continued to douse Ryan with a giant water gun.
Do boys ever grow up? It's OK, we don't mind seeing the "R.I.P.D" star in a soaking wet, skin tight shirt.
