Thanks for all the feed back.
Stephen Merchant I'll have to just risk! There are plenty of fat comics that mention their weight! As long as I keep the stuff specific I'll have to be pretty unlucky to stumble over the same gags. And its not like I'm not tall!
As to editing it down....i'm going to go back and listen to some stand up - maybe even write down their sets...because (although I'm sure you are all right) it sounds like how I'd say it...and how other comics talk. Dont they all ramble a little? I know it sitcom it needs to be stripped back and punchy...but don't stand ups "chat" a little more?
