Gas Men

Two gas company servicemen, a senior training supervisor and a young trainee were out checking meters in a suburban neighborhood. They parked their truck at the end of the alley and worked their way to the other end. At the last house a woman looking out her kitchen window watched as they checked her meter.
Finishing the meter check, the senior supervisor challenged his younger co-worker to a footrace down the alley back to the truck to prove that an older guy could outrun a younger one. As they came tearing up to the truck, they realized the lady of that end house was huffing and puffing right behind them. They stopped immediately and asked her what was wrong.

"When I saw two gasmen running as hard as you were," gasped the woman, "I figured I'd better run too!"
