Two employees for the gas company were at a house call. The younger man said to the older one, "Geez, you're old!"
"Yeah, that may be so, but I can still outrun you," replied the older employee.
"How about a foot race to see if you're right," said the younger employee.
With that they start running at full speed around that block. The older man kept up with the younger man around the first corner, the second corner, the third corner. As they come up on the last corner, the younger man sees an elderly woman running as fast as her legs could carry her. Puzzled by this, they both stop ask her why she was running behind them. The old woman caught her breath and said, "Well, you were at my home checking my gas meter, and when I saw you running away, I figured I'd better run too!"
