Psycho Clown mentioned in his comments today that his father died of a heart attack, which he had several of the last few years to the point they were doing Fritz Von Erich style fake heart attack angles with him.
Porky always reminded me of an alternate universe Terry Funk where instead of having two different careers as a technical wrestler and then a hardcore legend, he went from legendary trios wrestler (to the point it made trios a lucha staple) to being the greatest comedy wrestler there ever was. It was hard for people who only saw the comedy guy to believe the other version existed, but for someone to be that good at two completely different styles it speaks volumes.
