Walking up to a department store's fabric counter, a pretty girl asked, "I want to buy this material for a new dress. How much does it cost?"
"Blow me for ten yards" replied the smirking male clerk.
"Okay, then," replied the girl. "I'll take ten yards."
With expectation and anticipation written all over his face, the clerk hurriedly measured out and wrapped the cloth, then held it out teasingly.
The girl snapped up the package and pointed to the 75-year old hunch-backed old man standing behind her. "Grandpa's paying for it!"
