<"You may not use rage enhancing substances, such as caffeine, nicotine, alcohol, crack cocaine, slippy-flippy's, jelly stingers, trick sticks, bing bangs or flying willards. Also, if you are unable to stop masterbating please, do so without the use of any pornographic images depicting quote, unquote 'angry sex.' That having been said, I'm a pretty good guy and I think you'll be pleasantly surprised how much fun we can have together.">
<"Without slippy-flippy's or angry masterbating, I don't see how that's possible.">
