You and a few others made the same comment. Comedians are professionals who read a prepared script. All of them.
I was talking about genuine, spontaneous humor. Not in a setting where you're acting and where others know you're acting. Not when there's an audience. Spontaneously funny about bad things happening in real-time, in real-life, in a personal setting.
Even really good unhappy comedians would have a hard time with that one.
