Best Ways to Amuse Yourself at a Party

Everyone has been to a party where they were bored. Either they didn't know anyone, or didn't want to be out, or something else, but they ended up not having a good time. I think that is a crying shame, and I've come up with a list of suggestions to alleviate this problem, and hopefully it won't ever happen again. Here's the list:

1: Be the keg guy/girl - hang out at the keg all night long. Sooner or later, everyone will be by to say hello, and you never run out of beer in your cup.
2: Dance, but not well - this one is for those parties where you don't know anyone. Put on a snooty attitude, and then go dance as badly as possible. If anyone looks at you weird, give them as haughty a look as you possible can, and continue dancing. Hopefully you can convince others that you are the only "in" person at the party, and get them to start dancing like you.
3: Make bets about who is going to hook up, and then try to affect the outcome of the bet - everyone likes a party where they make money.
4: When no one is looking, change the CD's to show tunes. Bitch and moan when the host changes them for dance/techno. Repeat 15 minutes later.
5: Try to convince everyone that the keg is empty when it isn't - if they fall for it, take the keg into a private room/garage, invite your close friends inside, and try to finish the rest of the keg yourself.
6: Speak only in Lymerics (only for advanced amusers).
7: Try to convince as many people as you can that a small percentage of genetically gifted people can touch their elbows together behind their backs. It may not actually reveal genetically gifted people, but it will definitely reveal the "ungifted" (you'll know what I mean when you watch someone try to figure out how to get their elbows to touch for longer than 2 minutes).
8: Chair wrestling, enough said.

This list is not exhaustive, by any means, but it should be a way to start things going when you are bored. In fact, I think I'm going to try #8 right now, I'll let you know who wins...
