A Denver man was the recent victim of a prank by teenagers. According to reports, Stefano Chioetto was walking in the park last Thursday afternoon when he had to stop and use the port-a-loo. While he was inside doing his business, he felt the toilet start to move. He started shouting "Hey, Hey" until it eventually fell over. Luckily it fell on it's side and not on the door, so he was able to get out. According to witnesses, they believe it was teenagers. They say they saw them push it over and then run away. He did call the cops, but the teens were long gone before they got there. Stefano says he hurt his back in the process, and says the prank is no laughing matter.
