Hastings. Gettysburg. Normandy.
There were many great and epic clashes throughout history, but none so valiant (or ridiculous) as the one between this Boxer dog and this water gun.
In this video, uploaded by YouTube user Scipio12345, a single whistle -- the battle hymn of the backyard -- alerts the dog that something is about to happen. Then, the water gun strikes. Fire after fire, squirt after squirt, the two go head to head. Only one will be victorious, and it seems like the Boxer just might want it more.
Watch above to see who wins -- and who runs out of ammo.
