A friend of mine went to work for one of the smaller local departments, the kind with rather lax hiring standards...
He had a "co-worker" who was fond of stuffing his huge nickle-plated .44 magnum into his pants, sans holster. My buddy kept cautioning him against this practice, saying, "someday, you'll shoot your #$?! off."
Well, one day my buddy calls us on the phone, but he's laughing so hysterically it takes him five minutes or so to get a sentence out.
Seems the guy had shot his #$?! off....
Probably qualifies for a Darwin, as lack of further reproduction puts you in the running.
