A Lady was shopping at the local supermarket where she selected:
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 and
A 1 lb. package of bacon
As she was unloading her items on the conveyor belt to check out,
a fighter pilot standing behind her watched as she placed the items in front of the cashier.
While the cashier was ringing up the purchases, the fighter pilot calmly stated --
'You must be single.'
The lady was a bit startled by this proclamation, but was intrigued by the derelict's intuition since she indeed had never found Mr. Right. She looked at the six items on the belt and saw nothing particularly unusual about her selections that could have tipped of the fighter jock to her marital status.
Curiosity getting the better of her, she said -- 'Yes you are correct.
But how on earth did you know that?'
The fighter pilot replied -- 'Cause you're ugly'.
