Beyonce is rich, she's famous, she's hot. But that doesn't mean she gets out of working. Here's what she had to do for a day on the set of a Nintendo DS commercial.

Playing, watching, listening to Nintendo PR handlers, look at the camera, Beyonce, look at the camera, now look at the DS, sign some DSi handhelds, tell us about your first Nintendo game, can you sing the Mario theme song, can you shill the Wii please Beyonce...it's a full days work.

Reminds me of a dream I once had, where I was famous and doing the exact same thing. Except it was for Valkyria Chronicles, and I was paid in cupcakes...
