A woman walks into a supermarket and buys :
1 bar of soap
1 toothbrush
1 tube toothpaste
1 loaf of bread
1 pint of milk
1 single serving cereal
1 single serving frozen dinner

The guy at the checkout looks at her and says, "Single, are you?"

The woman replies very sarcastically, "How did you guess?"

He replies, "Because you're fucking ugly."
