Might be quite fun if you automatically got Hatsby'd/Trouted when you initially signed up to AIM, as an intro to the service - instead of the 5 or 6 complimentary spim-vertising bots you get on your brand new buddy list currently.
Wait a minute, this has happened to me during a lightning storm. The phone rang, and the caller insisted that I had called them. I thought it was just some freakish bug in the phone system caused by the storm, but now you made me wonder if it was actually a prank instead.
