Prick Minces A Dick

From Metro.co.uk:

Doctors' unions in Romania have criticised a decision to make a surgeon pay £100,000 in damages after he lost his temper and hacked off a patient's penis during surgery.

Surgeon Naum Ciomu, who had been suffering from stress at the time, had been operating on patient Nelu Radonescu, 36, to correct a testicular malformation when he suddenly lost his temper.

Grabbing a scalpel, he sliced off the penis in front of shocked nursing staff, and then placed it on the operating table where he chopped it into small pieces before storming out of the operating theatre at Bucharest hospital.

Which of course asks the question, what's the worst thing you've done in a fit of anger? Bonus points if your story involves penises, dismemberment or Tony Danza.
