Reminds me of a Jesus joke. The crowd was preparing to stone Mary Magdelen when Jesus comes along. Interposing himself between the crowd and the accused harlot, he shames the mob with "Let he who is without sin cast the first stone" Out of the crowd comes a little old woman with a 20 pound rock, nails the crap out of poor Mary and splits her head wide open. Jesus just shakes his head and says, "You know Ma, sometimes you really piss me off".
