Started on GameFAQs' Next Gen Gaming board.
A certain person, whose name I shall not name for...well, I dunno...purposes tried pwning someone, by telling him to take out the "su" in "superior" and put in a "in". This spells inperior. As you can see, the person was self-pwned. It was quite great, really.
By the way, the "superior" thing was actually the Gamecube version of Twilight Princess. That's how it started. MASSIVE DAMAGE!11111
First user: *awaits superior GameCube version of Twilight Princess*
Second, self-pwned user: You added an extra "su" and left out an "in" somewhere in that post...
