Frosted Flakes Ad Easter Egg - Tony the Tiger in Grocery Store

In the commercial featuring the over-zealous store clerk (he uses surveying equipment to make sure the shelves are perfect), there is a two-second clip of him facing the camera holding a box of frosted flakes telling you how seriously he takes his job. If you look carefully in the background, you can just barely see an animated Tony whiz by from right to left, tail wagging.
