10. Brotherly Love Stannie Get Your Gun
Let's get straight to the point, Steve makes out with his sister Hayley and we all watched it. It's not exactly Steve's fault after all it was Roger's little lie about Steve being adopted that sent the naive kid over the edge. His whole world has just been turned upside down and he's about to get his revenge. Steve initially takes his anger out by throwing a book shelf on Stan. Unfortunately Stan can't defend himself because he's in a wheelchair due to earlier antics in the episode. Steve then turns his attention to a shocked Hayley but she has no idea how weird it's about to get. When she questions her brother's behaviour, Steve, under the assumption the pair aren't related, responds with a scary line. "Something we've both wanted to do for years sis." And after emphasising on "sis" he forces his tongue down Hayley's throat while she squeals in disgust and Roger watches with glee. At this stage I think viewers are reaching for the bucket, especially if you and your sister are watching the show together, but can we really blame Steve in this situation? He is a horny teenage boy after all. The gross part is he says he's been wanting to do it for a long time, inferring that he's had some sort of thing for Hayley and only the fact that they were brother and sister had stopped his urges. Luckily it was just a kiss and nothing worse. Still, a pash and dash with his sister... did that really need to happen?
