Without knowing the specifics in this case I have to wonder why it is comedians are often personally such miserable people.
That seems to be phenonmenon of modern comedians. Bob Hope, George Burns, Don Rickles, Jack Benney, etc. did not seem to have this problem.
Most modern comedy is actually made up of saying very terrible things, scathing and contemptuous and mocking and foul, in a humorous way.
In other words, comedians are often not funny people, they just make you laugh. Sometimes, maybe all the time, despite your better judgement, or even despite the fact that you don't really want to laugh.
What they, the comedians, actually are, however, is often very angry or bitter people, with a very nasty mouth. Plus the ability to laugh while they are spewing foulness. People respond with laughter to deal with the stress of the resulting cognitive dissonance, not because they are amused.
My impression is that this is a more contemporary phenomenon. One can think of numerous comedians of our parents' generation and see that they seemed just as un-miserable off stage as on: to name a few, Jack Benny, Red Skelton, Danny Kaye, Will Rogers, Imogene Coca, Burns & Allen, and someone no one ever hears about now, Mabel Normand.
The best humor comes from miserable people.
Well adjusted people are not known for their comedy stylings.
Most Comedians today are Liberals and all Liberals are miserable people.
