Prank calling lots and lots of people from my hometown. I was home on a weekend, and we were bored. We had a buddy over and started prank calling people from the phone book. Beavis and Butthead was big at the time, and a line from the show was "Fire! Fire!" We quoted the show a bunch of times.
Unfortunately for us, one of the people we called didn't answer so we left a message for him. "Fire! Fire!" was included. His house burned down a few days later! We were caught up in a suspected arson case because of our message, caller ID, and our boredom.
