During Microsoft’s E3 2009 Press conference they showed a full body scanning peripheral called Project Natal (now known as Kinect) Kudo Tsunoda was doing a demonstration on how Kinect tracks your body.
However the on-screen avatar was glitched, with the arms and legs being twisted to unrealistic angles, then the avatar kicked and the sole of the avatar's left shoe was shown off. Kudo then provided the line “You ever wonder what the bottom of an avatar’s shoe looks like? Wabam! There it is!” in response to the glitched and twisted limbs on the avatar.
