Off the top of my head:

-fans killing people in Korea
-Hungarian suicide song
-ceiling fan decapitating bed jumpers
-automatically passing the semester in college if your roommate kills him/herself
-and so on and so forth

There used to be a show called Urban Legends that would talk about various Urban Legends. Now we've got MythBusters. Which is somewhat different, but still kewl (UL had a darker tonw, MB is more comedic).
