I'll follow that path...

I was shopping at the local supermarket where I 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.
A package of gum.

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 said, "Well, you know what,
you're absolutely right. But how on earth did you know that?"

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