Say it to yourself a few times. Vas Deferens... Vas Deferens... Vas Deferens...
That totally sounds like a boss of some RPG. He could carry around a giant bazooka and, um... And be in the ice dungeon... And he'd be like all "Blargh! Im Vas Deferens, gaurdian of the ice dungeon! If you want my key, you'll have to defeat me and my giant bazooka!" And then you'll be like all "Im only level 31! I can't defeat a bazooka that big!"
...
Yeah.
....
Vas Deferens.
He wouldn't take anyones crap, 'cause he's Vas Deferens.
