A woman was shopping at her local supermarket, where she selected a quart of milk, a carton of eggs, juice, and a package of bacon. As she was putting her items on the conveyer belt to check out, a drunk man was standing behind her, watching as she placed her items in front of the cashier.
The drunk said, "You must be single."
The woman, a bit startled, but intrigued, looked at her four items on the belt, and seeing nothing particularly unusual about her selections said, "Well, y'know, that's right. But how on earth did you know that?"
The drunk said, "Cause you're uglier 'n shit."
