"K&R" posts are always a great way to run up the count, and impossible to get wrong(Well, unless you knr something that's obvious tombstone material).
Adopt a persona and play it out consistently, including a character story line in your head.
DO NOT try to introduce rationality or facts into a discussion with someone who sounds like they're getting close to a lucid moment, the other sewer rats will smell you out in a heartbeat.
Although some have mentioned 'Over the top,' well, still be careful about laying it on too thick, too fast, and too weird. Make what you say actually plausibly consistent with your chosen persona.
