Dipstick

A woman pulls over at the gas station, gets out of her car, opens the hood, and checks the engine oil. After a few seconds of intelligent thinking, she takes a dipstick in her hand and, raising her chest high, walks up to the attendant: "Excuse me sir, but can I buy a longer dipstick?"

"May I ask why you need a longer one ma'am?"

"Because this one isn't long enough to reach the oil!!"

Hahahahahahaha :P
