They don't. And when their wife comes home a dialogue ensues that usually goes something like this:
"Honey, you were supposed to mow the lawn today."
"But I did dear."
"Then why is the grass nearly a foot high?"
".....someone must have added that grass after I finished mowing the lawn."
Their poor wives can never win. And if the wife ever tries to file for divorce, her husband will prove to the judge that the divorce papers are not authentic.
