I am saddened to hear this. Peter was a nice guy, I remember before Game Show network went officially on the air they were doing LIVE tests on the Satellite (C Band) and Peter was the host asking people to call in and play the game they were doing.
He was just sitting there making jokes how no one was watching so I called in and got on the air and got to play the game with him on the air for no prizes. It was fun to do. About a week after I did that Game Show Network went on the Air officially.
I remember watching the reruns on USA in the mid 90's and also remember the special where the guy figured out the patterns and kept winning. I think he quit on his own on trying to win anymore because he got tired of trying to win.
