A guy from Texas is invited to a Halloween costume party while in Chicago on business so he visits a costume shop.
He says, "I'm going to a costume party, and I want to go as Adam."
The girl looks him over, and then brings out a fig leaf.
He says, "Not big enough."
She brings out a bigger one.
He says, "Still not big enough."
She brings out a huge fig leaf.
He says, "Honey That's still a little on the small side....."
Not impressed she says, "Listen, Tex, why don't you just throw it over your shoulder and go as a gasoline pump?"
