"The Wizard". I think I was 13 or 14 years old. Apparently there was an accomplished phreak that went by that name as well. One afternoon I got a phone call by a bunch of phreaks on a conference call asking me if I was The Wizard who hacked such-and-such and would I like to write a text file for them on it. I told them I wasn't that person, but they still invited me to stay on the call. I stayed on and listened for hours and hours as they talked about trunks and switching systems, blue boxing, and all kinds of amazing stuff.
