This is what separates from the every day poodle flaunting snake hating (insult goes here) pet keepers.

Snakes aren't your average pet, as I'm sure you know. You are going to eventually get bitten, sorry there is no way around it. Just pick him up like a doughnut, and do not release him when he bites. That way, he'll learn that biting you is inane and he will eventually stop.

Just don't do it too much, if he gets too stressed he will stop feeding.
