-On the "infinite staircase" on the original Super Mario 64, if you long jump away from the staircase and hold back towards the staircase, Mario will start sliding up the backwards on his butt while saying tons of "Yahoo!"s. This glitch lets you beat the game quickly since you don't have to collect the amount of Power Stars that deactivates the never ending staircase.
It's my job to help the next generation, and set a good example for them. And for that I'll gladly lay down my life.
