Rick Wilson is a cranky, elderly, fundamentalist christian who is so extreme in his beliefs that normal Christian folks are ashamed to be even associated with the guy. He thinks anything and everything will send people to Hell unless they go word by word in the bible. He always carries this bible around and never lets go of it, even in the shower.
He even tells other Christians they'll go to hell because they're simply having fun and enjoying their lives. He tends to walk inside Mike and friends houses and preach to them to "change their ways" or they'll be sent to Hell, only for him to get booted out a few minutes later.
Rumor has it that he was seen with the RUC.
