another urban legend from Belgium is about a gang in a certain city (don't know which). you can find them in subway stations, and if you meet them they give you two choises: groepsverkrachtig of engelenlach (gangbang or 'angelsmile'). and if you make the better sounding choise angelsmile, they take a knife and cut the two ends of your mouth open, right to your ears. so you'll get an angelsmile indeed...
good this one isn't actually true, but you better pay attention in stations though...a guy named Joe was killed two weeks ago in belgium. two polish dudes (they were gypsies (is that the right word, not discriminating or something?)) wanted his mp3-player. he didn't gave it, so one of the dudes decides to stab him 5 times with his knife, result: joe is dead, just because he didn't want to give a music player...
they found one of the polish guys a few days ago, and the murderer today.
