The most famous comedians are often better known for their moodiness and sudden rages than for their joke telling.
Think of Milton Berle. Boy, could he get angry offstage!
Jerry Lewis; snippy to co-workers, cruel to his family.
Bill Cosby; Superbly talented, but ‘hobbies’ unbecoming.
I loved Bob Hope for decades...until I saw him be really mean to his wife. Couldn’t stand him after that.
