South Park Easter Egg - Hidden IM Message

In the episode 'Cartman joins NAMBLA', Cartman is looking for companions on his computer and is in a chatroom he types in something about being a young boy and receives a lot of replies. If you have the DVD or this episode on tape, play it in slow motion before all the replies pop up. Eventually you will see one that says "r u actually reading these" and the one after that says "get a life".

NOTE: this happens after the first man is arrested (the second time Cartman is online).
