I would hate to be a stand up comedian. I don't think I could ever be pressured into being funny like comedians are. Thing is, truly funny is spontaneous in my opinion, and I'm not saying stand-up isn't funny. Stand up is fucking hilarious.
I could never rehearse jokes, have them written down and then remembered. Then standing in front of people, thinking how much I'm being paid, and then telling the same jokes I've been telling for months now.
So kudos to you, stand-up comedians.
