A guy shopping at the grocery store goes to the express lane with the following items:
1 pint of milk
1 short loaf of bread
1 small jar of peanut butter
1 grapefruit
1 pack of single-serving canned tuna
1 box of instant soup mix
1 small jar of spaghetti sauce
1 frozen dinner

The young lady at the register scans each of the items and says to the guy, “Well, I guess you’re single, aren’t you?”

He rolls his eyes and says, “Gee, how could you tell?”

“Because you’re ugly.”
