As far as I know it's not on till Thursday so you'll have to wait. The whole concept is dated, done many times by cretins like Dom Joly already and way past the point of being funny or original. ie I agree with you.
I watched the first of this new series last Thrusday night. It's a pretty simple concept, but I found it pretty funny. Some of the pranks were funnier than others though. I would watch it again, but I won't be that bothered if I miss it.
I used to listen to a radio programme very similar years ago, I didn't realise there was a similar programme on telly, I can't wait for Thursday now - thanks I need a good laugh
