"The Gas Man Runneth" joke

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 one end of the alley and worked their way to the other end. At the last house an older woman was looking out her kitchen window watching the two men as they checked her gas meter.

Finishing the meter check, the senior supervisor challenged his younger coworker to a foot race down the alley and back to the truck to prove that an older guy could outrun a younger one.

As they came running up to the truck, they realized the lady from that last house was huffing and puffing right behind them.

They stopped and asked her what was wrong.

Gasping for breath, she replied, "When I see two gas men running as hard as you two were, I figure I'd better run too!"
