Super Mario 64 Glitches

Swim Without moving!
I'm not a glitcher, but I did find a cool glitch in Super Mario 64. At the place where you start the game, get the Wing Cap. Launch onto the castle, then jump off. Repeat. In mid-flight, your Cap will (should) wear off. DON'T TOUCH ANYTHING!!! The game should make you land in the moat (it needs to be full of water) near the wall opposite the castle, then you'll swim along the wall using Mario's "treading water" animation!
