This week on the Nintendo Channel: Celebrities, Mac and Cheese

Another Monday means another Nintendo Channel update, and this week we've got a boatload of new video content, as well as some new DS content to love. On the demo side, there are two piping hot samples, one of which is Personal Trainer, and the other TrackMania DS. Check the full list of demos after the break.
