Jimmy Fallon and Daniel Radcliffe engaged in an all out war on NBC's 'The Tonight Show' last night. The chosen method of battle? Throwing sticky balls at each other.

Radcliffe was on 'The Tonight Show' to promote his upcoming Broadway play, 'The Cripple of Inishmaan.' In what seemed like a way-more-fun version of dodgeball, Fallon and Radcliffe each wore velcro jumpsuits and threw brightly colored velcro balls at each other while limiting themselves to one half of a darkened cage made of fabric. The object of the game was to throw as many balls onto the other person in 45 seconds and at the end, the person with the most balls stuck to his suit is declared the loser.

We won't spoil who came out on top, but the winner won handedly by taking his time throwing a few balls at a time. The loser, however, tried a different strategy and threw as many balls at once, as his hands could hold. This method did not work, as you will see at the end. It's a good thing to know, if you ever end up in a sticky balls battle.

Watch Fallon and Radcliffe's epic fight and as well as a few jokes here and there about touching and grabbing balls.

Boys will be boys, we guess.
