Looking for jokes about drunks

A woman was shopping at her local supermarket where she selected:

a half-gallon of 2% milk,
a carton of eggs,
a quart of orange juice,
a head of romaine lettuce,
a 2 lb. can of coffee and
a 1 lb. package of bacon.

As she was unloading her items on the conveyor belt to check out, a
drunk
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. Curiosity
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."
