I was shopping at the local supermarket where I selected the following items:

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
As I was unloading my items on the conveyor belt to check out, a drunk standing behind me watched as I placed the items in front of the cashier.
While the cashier was ringing up the purchases, the drunk
calmly stated, ''You must be single.''
I was a bit startled by this proclamation, but I was intrigued
by the derelict's intuition, since I was indeed single. I looked at the
six items on the belt and saw nothing particularly unusual about my
selections that could have tipped off the drunk to my marital status.
Curiosity getting the better of me, I stated, '' Well, you know
what, you're absolutely right. But how on earth did you know that?''
The drunk replied, ''Cause you're ugly.''
