I like what he does when under con-troll. That's when he's at his zaniest.
Though he's aware he's being watched, he's unaware of the script. Its the closest thing we have to a real Trueman Show.
The whole "what can we get him to dress up as next?" theme going on now isn't really that entertaining, but I do think that Chris is at his best when he's being trolled. Their best work was the whole fake Chris/fucked up love triangle thing they had going on.
