Comedians should receive some kind of immunity because they’re comedians, especially when they are doing their comedy. Comedy is a kind of performance, and there are all sorts of things you can say in a performance that you can’t say in any other social situation. There is nothing wrong with an actor in a movie saying “put all your money in this paper bag or I will shoot you between the eyes”. But he can’t say it while standing at the front of a line in a bank.
