I was wondering, wouldn't it be good to see Derren Brown on the program Poker Face?

I mean, the amount of things he could do, the possibilities would be endless!

-He would be able to tell whether people were lying or not

-Use 'Anchoring' (I am not worthy to say the word without quotes) to make contestants think they are bottom of the leaderboard or the top of the leaderboard when it is the complete opposite!
-He could tell people whether to fold or not, depending if he felt in a good mood or not (person A is about to fold, he says "STOP!", saying they will stay in, then he saves them and they go on to the next round!)
-The above could be used in a bad way, if he wanted the person to leave with nothing

I thought I would just mention it. Post any ideas you have to what he would be able to do!
