What have you done in the bathroom (besides the obvious)?

Seems to me that a lot goes on in bathrooms that no one ever talks about. I remember the story I heard once about someone who dropped acid in the bathroom, and never left the place, because she couldn’t find the door (I think it was the wallpaper). Bathrooms seem to be pretty notorious at parties—the only place you can have some kind of privacy. Anyway, I’m sure, in this crowd, there must be all kinds of things I can’t even imagine. Do tell. In as vivid details as you can manage.
