My material is unscripted, I don't care if you believe that or not that's irrelevant to me.
If you took time to listen to a few you would realise that as no one can read or memorise the stuff I say three times a week and not sound like a robot.
I'm not claiming to be anything amazing here and if you don't like my material and don't find it funny that's fine, but why do you feel the need to put a comment that might well put other people off from listening?
That's also a school boy error as it makes you look weak and narrow minded, I understand that stand up guys could well be in competition with each other (and also speech and script writers like yourself) but I don't do stand up, because like you say doing unscripted stand up is a whole new ball game and is unlikely to work.
I sit in front of a microphone with some newspaper articles/ or facts/ or websites, read them and then say what I think about them in hopefully an entertaining manner, to me that's natural, is it for everyone, no, does everyone find it funny, no, but I enjoy it so I keep doing it.
