Zonker: So what do you want to do in college, Zipper? Zipper: Well, I was thinking of being a football star like you, Uncle Zonker! Zonker: Outstanding! I didn't know you played football. Zipper: Well, I don't, but look at the dummies who play it - how hard could it be to learn? Zonker: Good point. Just don't get all hung up on the rules. Zipper: Football has rules? Zonker: Well, it has refs, and they like to keep busy.
