Walking up to a department store's fabric counter, the pretty girl said, "I would like to buy this material for a new dress. How much does it cost?"

"Only one kiss per yard," replied the male clerk with a smirk.

"That's fine," said the girl. "I'll take ten yards."

With expectation and anticipation written all over his face, the clerk quickly measured out the cloth, wrapped it up, then teasingly held it out.

The girl snapped up the package, pointed to the old geezer standing beside her, and smiled, "Grandpa will pay the bill."
