Rule #90 

Trolls are always trolling. Trolls will troll in every sentence that they speak, or write.

Fred: I met this guy, he said he was a troll but he wasn't trolling me.
George: Rule #90 bro. Trolls always troll.

Runescape 

A game created by Jagex that a lot of people bash and make fun of for being "gay" and "nerdy". I didn't think much of it at first, but I created an account. And the snowball effect set in. Runescape is honestly the most addicting thing I have ever done, forget just limiting it to games. Runescape will turn you in to a monster. You won't care to hang out with friends (unless they too play Runescape), you will snap at your family when your gaming time is in jeopardy, you will not care about anything that you once cared for. In all honesty, it's a pretty sweet game. It's moderated fairly well, the quests are really fun and some challenging, the monsters are fun to fight, and it's a decent game all around. But don't get sucked in. Because it is almost impossible to climb out of the hole.

Me: Hey guys! What are you playing?

Friends: Runescape, it's an online role playing game.

Me: Hm. Sounds interesting.. Mind if I make an account?
Friends: Sure, we'll help you!

Me: ..

NOOOOOOOOOOOOOOOOOOOOOO.

The Rakesh Paradox. If something Random is said do not reply, or continue it into a conversation, it will only make things worse. If there is a reply, the person replying must be hit 3 times on the arm with a kettle.
