Randy: Don't worry. We're gonna get 'em back good. Look at this.
Mark: What is it?
Randy: It's a catapult. Look at the picture. In Middle Ages, when you wanted to storm an enemy's castle, you'd get a dead and diseased horse and fling it over the castle walls.
Mark: You don't have a dead horse.
Randy: Hey, maybe we could get Mrs. Bauscher's dog.
Brad: He's not dead.
Randy: Well, almost.
Brad: We just need something that stinks. [both look at Mark]
Mark: I don't stink.
Brad: Garbage. We could build one of those things and fling it into the back of McGurns' yard.
