Shopping At The SuperMarket

A girl walks into a supermarket and buys the following:

1 bar of soap
1 toothbrush
1 tube of toothpaste
1 loaf of bread
1 pint of milk
1 single serving of cereal
1 single frozen dinner

The checkout guy looks at her, smiles, and says, "Single,huh?"

The girl smiles sheepishly and replies, "How'd you guess?"

He says, "Because you're ugly."
