Also, if someone's making small talk while waiting for everyone to show up and asks if you have anything special planned for the weekend, it is apparently NOT acceptable to say "Oh, you know, the usual. I'll strip naked, coat myself in Vaseline, put a plastic shopping bag over my head, cinch a belt around my neck and tie it to the closet bar and jack off to German dungeon porn until I either come or pass out. If I'm here Monday, you'll know which."
