Draft:L is real 2401

A rumor about the 1996 video game Super Mario 64, called L is real 2401, suggests that Luigi is an unlockable playable character.

Background
In every previous Super Mario game, Luigi was a playable character, but is nowhere to be found in 64. A statue near the entrance to the level Big Boo's Haunt has an engraving left up to interpretation, with some players reading it as "L is real 2401". This lead to people believing that Luigi could be found in the game somehow.
