In Chicago in 1978 or so he attended an event at Northwestern as an alumni. Later he was in a McDonalds and caused quite a bit of havoc. It appears he was quite a biggoted person. He got started on some of the help that worked at McDonalds, calling them all kinds of nasty names. He ended up in jail for a few days over that one.
But right at the end, he tried to clean up his act, lose some weight and stop drinking. But alas, the damage had already been done. I heard he had the organs of an 80 year old man even though he was only 55 at the time.
I thought he was hilarious but if you watch him for any length of time it is apparent that he's the same person in all his roles, just the name of the roles change.
