A young woman sat in her stalled car, waiting for help. Finally, two men walked up to her.

"I'm out of gas," she purred. "Could you push me to the gas station?"

The men readily put their muscles to the car and rolled it several blocks. After awhile, one looked up, exhausted, to see that they had just passed a gas station.

"We just passed a station! How come you didn't turn in?" he yelled.

"Oh, I never go there," the girl shouted back. "They don't have full service."
