lol Im the most l33t here I remember when I started coding with C++ console and I learned how to make a sound from the CPU then I coded one program to make the song constantly so it sounds like pipipipipipi* lolz my program is here:

LOL I did that once, too! And the other students were asking how I did it, and I just told them to press the shift key several times!!! And they were so impressed too!
But my best hack was when I figured there was a bug with the RAT program out teachers used, which allowed me remote shell access, and exploiting that bug, I was able to shutdown my teachers computer plus about 20 other teachers randomly!
But I was not as lucky as Techb. I told my teacher right away about the bug, and told him to fix it, but instead of getting extra credit, I almost got yelled!...
Another one was when I tried cracking the admin password by booting up ophcrack on the dell laptop in our school, in the middle of the class while the teacher was lecturing, and got caught! Imagine me, and 20 other students, in the class, everyone silent, and the teacher asks me: "Hey what are you doing?"... Fortunately, I got away, playing innocent, telling him that it was just my "own operating system!" lol
