A woman goes to the grocery store and carefully selects a pound of bacon, a gallon of milk, a loaf of bread, and a carton of eggs, then gets in line at the checkout counter.

As she takes the items from her cart and loads them on the conveyor, she notices the man behind her is watching her.

As she puts the last item on the belt, the man says to her " I bet you're single"

She says "That's amazing, I am single, how did you know that?"

He replies "Because you are #$%#ing ugly"
