I had a similar situation when I was 14 years old making prank phone calls. It was 26 years ago and I stumbled on a block of numbers that contained every phone company error message. You know... You have to dial 1, Don't dial a 1, deposit a quarter, etc. Most of those numbers work to this day - 215-257-0012 to 215-257-0017. The best trick I ever did with them was to record the message, "We're sorry, you must first a dial a 1 to call this number" message onto my answering machine when I was 21. People would call me, get my answering machine that told them to a dial a 1, hang up then dial a 1 and then get the real phone company error message, "We're sorry, it is not necessary to dial a 1 when calling this number." I didn't get a single message for two weeks since people were basically caught in an infinite loop. I thought it was pretty funny until I came home from work one day and the phone company was digging holes around my house. Apparently my mother reported a problem on my line to the phone company who couldn't figure out how the hell my line got mixed up like that so they just started digging.
