Two gas company servicemen, a senior training supervisor and a young
trainee, were out checking meters in a suburban neighborhood.  They parked
their truckat 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 the two
men as they checked her gas meter.

Finishing the meter check, the senior supervisor challenged his younger
coworker to a footrace down the alley 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 figured I'd better run too!"
