So there's this guy who is all excited about joining the army. He heads for the local recruiter's office and says he's psyched to join. The recruiter says "Hey, great! Here's your gun," and hands the new soldier a broomstick.

The new dude says, "Hang on, what kind of a gun is this? It doesn't even have a bayonet!" The Sarge ties a piece of string on the end, and says "You're all set now, just head out to the battle front, point your gun, and say 'Bangity-Bangity-Bang' and the gun will work fine. Swing it around, and say 'Stabity-Stabity-Stab' and the bayonet will do its thing." The soldier is a skeptic, but he's also not the brightest guy, so he believes the Sarge and heads for the battle front.

There he is, in the middle of all the fighting, with a crazed look in his eye. He picks up his trusty broomstick, and waves it around at the enemy, saying "Bangity-Bangity-Bang!, Stabity-Stabity-Stab!, Bangity-Bangity-Bang!, Stabity-Stabity-Stab!" To his amazement, everyone on the field is completely wiped out. Everyone, that is, except for one fighter, who is advancing very slowly and steadily toward our hero.

The soldier thinks, "Hey, no sweat," and aims his broomstick. "Bangity-Bangity-Bang!" No difference -- the enemy soldier keeps advancing, slowly and steadily. Our man waves his weapon threateningly and says "Stabity-Stabity-Stab!" Still nothing. The enemy advances steadily toward the soldier. He bumps into the soldier, knocks him down, advances up over his legs, stomach, chest, and face and continues over the other side - slow and steady. As the enemy moves away, the soldier hears him saying "Tankity-Tankity-Tank."
