Eternal invinsibility (as long as you don't move)

From Glitches

From the game Super Mario 64 for the Nintendo 64.

Go to the 2nd level (Whomp's Fortress or something) and run into a sleeping (or awake) Piranha plant. Now, while you're recovering and flashing, stand right where the piranha is, so that you're going through him and he's trying to bite you. Now, just stand there... you'll keep your invinsibility as long as you don't move outside of the piranha plant.
