Super Mario 64 Glitches

Hang On Wall While Dead
In Wet-Dry World, get into "town", drain the water, and get your life down to two pieces. Go to the platform with the highest diamond but don't touch it. Jump toward the cage and if you're lucky, you will land on the thin wall, lose the last two pieces of life, and grab onto the wall. You will still die as soon as you let go or climb up!
