Two gas company servicemen were calling on houses in a neighborhood, checking the meters. At the final house on their round, they noticed an attractive lady watching them through the window as they checked the meter.

Their truck was parked at the end of the street and, to prove his fitness, one man challenged the other to a race. As they ran to the truck, they were surprised to find the woman huffing and puffing right behind them.

"What's the matter?" they said.

She gasped, "I don't know about the rest of the people in the neighborhood, but when I see two gas men running away as fast as you are, I'm running too!"
