High school CS was my first exposure to what 'hacking' usually is. Grade 11, we were learning VB6 (don't ask). Our term project was to make a game, and three of us decided that we wanted to make a top-down shooter that had networked multiplayer. We soon figured out that only teacher accounts could see other computers on the network, so the obvious solution was to obtain the teacher password. Cue 48 hours straight of my poor 200Mhz Pentium Pro (with MMX!) trying to crack the SAM file, with no success. Frustrated, I was in the lab after school and went to grab a paperclip from the teacher's desk to reset the BIOS password. Open the drawer, and what do I see? The teacher's login and password written on a sticky note.

The game actually kicked ass, and the teacher never did figure out how we made the multiplayer work. We told him "it uses socks".
