Norman suffered a completed mental breakdown (I believe he was on a small boat at the time). Many entertainers not only comedians have issues like bipolar, depression and others. Stephen Fry has bipolar, Vincent Van Gogh, Winston Churchill to name a few and many explorers had ADHD with incredible drive and determination with excess energy.

I saw Gary McDonald live in a workers club somewhere. He also did a character called Phil A. Stein, supposedly the entertainment manager of the club. I didn't recognise him at first. Very funny.
Oh, and thanks Recoup, I wasted all yesterday afternoon watching YouTube comedy sketches. You well and truly sucked me in.
