I'm pretty sure the real Rodney doesn't do that

Question for the cat owners on my flist:

Is there a way to train a cat out of a bad behaviour? Like, for instance, biting?

I would appreciate your thoughts and any advice, as the Rodney-cat is banned from my room at night until such time as he stops biting me. Even now, he's sitting on my lap and I can just see the look in his eyes that is saying "I want to take your hands off".

Also, he burrows in under the covers to bite parts of me that are inaccessible.
