The kiss of death for many a standups 'stand up' career is getting a TV show.
Well yes you get lots and lots of cash for a while but suddenly you dont have time to write new material because your too busy filming. So sooner or later you people start to get a bit pissed off with paying upwards of £50 to see you tell the same jokes they've seen you tell on TV on almost a monthly basis (thanks to channels like Dave). The double edge sword to this is with TV shoes they have to relying on 'scriptwriters' just incase they dare say anything that may upset somene (Be offended. Its good for you. It allows you to grow!!!)
And as with Michael Macintyre, Frankie Boyle, Jason manford, Russell Howard, etc they're touring days will come to a halt with a bang. If they are smart they will get out while they are still at the top of their game or in the case of manford become a teatime TV host (those gigs tend to last much longer than comedy).
Then of course you have the likes of Andy parsons who I still have no fucking Idea why he is even classed as a comic.
Or am I weird in believing a joke is funnier when the punchline isnt explained to you?
I will be interested to see what people think of peter Kays upcoming tour. After all the arrogant cunt gave himself a year to think up the jokes.
