A man is working cash at a grocery store. A lady walks up and starts to place her items on the belt.
The man looks down at the items she had laid out. There was a carton of eggs, a gallon of milk, and a head of lettuce.
The man looks at the woman and says “you must be single”.
The woman looks around surprised, saying “yes I am! How did you know?”
The man responds “cause you’re ugly”.
