Danone Activ (Calcium Water) - Skate Board Injury!
There are two animated skeletons, Toby and Charlie (I think). Toby Skeleton's friend Charlie goes over a ramp on a skateboard and loses his balance causing him to fall to the ground and shatters into pieces, but when the camera follows him to the ground, he's back in one piece again. If you look VERY carefully, you can even see at one point Charlie was a skull.
