I know he's more than likely an alcoholic or druggie in some way,. and i obviously dont believe the alien nonsense., but i gotta say i think i believe what he says about Sirius screwing him over all the time. I can see that happening no matter how far fetched they make his sound bytes seem.
Lol plus his voice makes me laugh. Just his voice. Haha. I just like his character, legally insane or not.
