Most TV shows don’t reward you for paying attention.
It’d be disingenuous to say I don’t like attention – I’m an actor for God’s sake – and it’s flattering and all, but attention was never my big goal. I just like to work and have a good time.
Humor is richly rewarding to the person who employs it. It has some value in gaining and holding attention, but it has no persuasive value at all.
