Work parties - what happens when people don't follow the rules?

The Times Online today has an article about what not to do at work parties if you don't want to sabotage your career: Dont have bad breath, dont get drunk, pace yourself and dont embarrass yourself on the dancefloor. Not exactly rocket science. I am a firm believer in learning from other people's mistakes.

So, what is the worst thing to have happened at your work parties? Add your comments but please be kind and remove real names.
