Worse things to happen at parties:
Fall asleep on the toilet (don't forget to lock the door)
Be sick on your partner/crush
Drink Turps when under the impression it's vodka
Drink chicken fat (that wasn't me!)
Burst in on a couple having sex with a chorus line of ppl singing "New York New York"
Start philisophical debates with creepy people in the kitchen
Threaten to throw some one off the balcony for shouting at foxes
Watch the foxes from 11pm till 3am and speak to no one
Stretch out on the couch and either fall asleep or grumble irritably at anyone who dares try to sit on it
Spill drinks
Hoarde the food
Throw the food
Fire Kumquats out of a balloon
Don't attempt the above with eggs
Practice wrestling moves on friends and strangers alike
End up in the room beside the humping couple
As for video games while drunk, I've seen it done, also I was recognised as unbeatable at Soul Edge (Soul Blade here) on the PSone. A guy tried fruitlessly to beat me at it at a party. I woke up when I heard a cheer, the guy (Gary) had just celebrated his victory over me, till someone pointed out I had fallen asleep during the fight...
