An elderly couple return to a Mercedes dealership to find the salesman had just sold the car they were interested in to a beautiful, 
leggy, busty blonde. 
 
"I thought you said you would hold that car till we raised the $75,000 asking price," said the man. "Yet I just heard you closed the deal for $65,000 to that lovely young lady there. You insisted there could be no discount on this model."

"Well, what can I tell you? She had the ready cash, and just look at her, how could I resist?" replied the grinning salesman.

Just then the young woman approached the old folks and handed them the keys.

"There you go," she said. "I told you I could get this joker to drop the price. See you later, grandpa.”

Never mess with the elderly!
