A guy goes into a costume shop. He says, "I'm going to a Halloween party, and I want to go as Adam." The girl brings out a fig leaf. But he says, "Not big enough!" So she brings out a bigger one. "Still not big enough!" So she brings out a HUGE fig leaf. "Still not big enough!" he proudly tells her. So she says, "Listen, Ace, why don't you just throw it over your shoulder and go as a gasoline pump?"
