Do you like this one?

A woman was shopping at her local supermarket where she had selected the following items: A half-gallon of 2% milk, a half carton of eggs, a quart of orange juice, a small head of romaine lettuce, a 2-pound can of coffee and and a 1-pound package of bacon. As she was unloading her items on the conveyor belt to check, a drunk man standing behind her watched as she placed the items in front of the cashier.

While the cashier was ringing up her purchases, the drunk calmly stated, "You must be single."

The woman was a bit startled by this proclamation, but she was intrigued by the derelict's intuition, since she was indeed single. She looked at her six items on the belt and saw nothing particularly unusual about her selections that could have tipped off the drunk to her marital status. Curious getting the better of her, she said "Well, you know what, you're absolutely correct. But how on earth did you know that?"

The drunk replied, "Cause you're ugly."
