Please, clear all your children out of the room, because an unnerving discovery has been made about Mario Kart DS: It knows whether you are using a Phat DS or a Lite DS! Don't scream just yet. Watch the video first.

When Mario Kart is started on the Phat DS, it greets the player with a few engine roaring sounds and Mario's voice saying, "Yahoo!" But, when the game is started on a Lite DS, the player is greeted with engine roaring sounds and Mario's voice saying, "Here we go!"

Coincidence? I think not! This odd phenomenon leads to some questions: Does Animal Crossing know if you are wearing boxers or if you are wearing briefs? Does Brain Age memorize your alcoholic beverage preference? Does your mother know you're in a relationship with Luigi? Updates will be posted as we exploit these insightful inquisitions.
