Wet Pants
Cassie was a really good mom. When her children were growing up, her one son gave her more "stop and count to 10" periods.
Once, after her small son fell into the pond and came home with his good school clothes dripping wet, the exasperated Cassie sent him to his room while she washed and dried his clothes.
A little later, Cassie heard a commotion in the back yard. She called out "Are you out there wetting your pants again!?"
There was dead silence for a moment. Then a deep, masculine voice answered meekly, "No, ma'am, I'm just reading the meter."
