I certainly did my share of prank calls when I was a teenagers. Hey, what else is there to do in a small town when you are 14 or 15?? One of my favorites (with my best friend/cousin on 3 way) was to call some geeky/weird boy and tell him that I had a crush on him. I would call her high school and she would call mine (wouldn't want anyone to recognize my voice). We would tell them to meet us at a sporting event/skating rink, etc. the next week. We would die laughing when they showed up looking for their crush. Now that I think about it, that was really mean!!
I hate people who do the *69 call back thing though. "I received a call from this number." is just stupid.

If I had wanted you to know I called, I would have left amessage!!
