Jimmy Fallon makes the classic kids card game 'War' awesome -- and probably very cold -- by adding a water element. He challenged Hugh Jackman to 'Water War' on 'Late Night' (Weeknights, 12:37AM ET on NBC).

The version they played had them soaking each other after every turn of the card, or victory if war is declared. They were soaked immediately, but it did make for a fast and fun series of soakings. And if you were interested in seeing either of them in a wet shirt, there you go.

For the home version, we'd recommend only dousing your opponent after each victory in a declared war round. That way, the water lasts a bit longer, and the anticipation is even greater and more terrible!
