Maybe it's just another one of his publicity stunts? We can only hope.
For those of you who weren't paying much attention, you might know George Plimpton as one of the psychologists Will Hunting visited in Good Will Hunting, and he took a number of bit parts and cameos in other movies.
He was also the "spokesman" for Intellivision back in the day. There was a great spot with him and the kid who played Elliot in ET where Elliot says "Hey, aren't you Intellivision guy?" And Plimpton slips him a copy of a hot new game and asks him "What's your name, son?" And the kid acts amazed that Plimpton doesn't recognize him.
