Ha, I listened to that yesterday. Yes, he is way fatter, I'd say 20-25lbs bigger since the start of the Fitmisc thing. And he is being driven nuts by it. He thinks Norton is going to pay someone to jump or kill him if he meets him anywhere. He is also trying to play it off like the cops told him there is a legitimate threat on his life.
If it was anyone else, I'd believe it was an elaborate Andy Kaufman-esque troll job, but him and his girlfriend real do seem to be feeding each other's delusions.
