The worst thing I probably did ever was laugh at this. However, I am baked so I will compensate with that.
Actually, I can't really bring to mind any really bad :skull::skull::skull::skull: I've done ... I can be a prick to people, but only if I really don't like them. I have a habit of talking about people loudly when they're in the same room.
I also used to steal toys from my friend's when I was a younger bugger.
I would be pretty upset if someone did this to me, actually. Not so much because it's my MYSPACEPAGEOMFGWHY but because I have a :skull::skull::skull::skull: load of pictures on my myspace that I don't have saved anywhere else and would be rather upset if they were deleted/removed/edited in some way.
