As she was unloading her items on the conveyor belt to check out, a drunk standing behind her watched as a woman placed the items in front of the cashier:
A half-gallon of 2% milk
A carton of eggs
A quart of orange juice
A head of lettuce
A 2 lb. can of coffee
A 1 lb. package of bacon

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

She was a bit startled by this proclamation but, since she was indeed single, intrigued by the derelict’s intuition. As she looked at the six items on the belt she saw nothing particularly unusual about her selections that could have tipped off the drunk to her marital status.

Curiosity getting the better of her, she said, "Well, you know what, you’re absolutely right. But how on earth did you know that?"

The drunk replied, ”You’re really ugly."
