Don't go parking by a bridge that has a dead-end with a girl unless you want to get hooked and not in a good way. This guy punishes and not with a fun spanking either. Also have this guy pull up his pants because I don't really want to paint that certain spot unless of course it happens to be Dean or Sam. Why do you want to look like a giant grape for anyway? I've never understood that but I've never been all insane about sports either.
There's also the lesson of not melting down the killer's hook and turning it into jewelry since that could come back to bite you on the ass big time. So do a background check on any family heirlooms to avoid accidentally sending a killer spirit against anyone that pisses you off. Yeah that would be kind of cool except for the whole killing part.
