Andy himself was meant to have posted something on here already, but he probably hasn't gotten his lazy arse round to doing it. My apologies. I'm sure he will...soon.
As Andy sees it, if there's a series about him, he wants to be present to make sure nothing untrue is said and defend his mental ability (now that I have to see).
Basically, his friends and I believe him to have a brain with the equivalent mass of a hamster, except a hamster at least keeps active on its wheel...and some of us believe the hamster powering Andy's brain has long died from depression at his stupidity and the odd thought that comes out, does so only when the wind happens to come in through his ear and blows the wheel to turn a little.
