I once beat Super Mario Bros. 3 from start to finish without warping 3 times in a row because I had nothing else to do.

I once beat FF1 without any fighting characters for "fun".

I once played Volleyball.

I once beat level one in Championship Loderunner.

I once played Arkanoid until I got bored, in stead of until I died.

Scott once defeated the OSG himself at Pro Tennis (Camerica). Damnit! I had forgotten about that!
