The video below is of some kind of competition to see which dog can race down a track fastest. The catch is that on both sides of the track are placed distractions in the forms of treats and toys and it takes a certain single-minded focus to ignore those and proceed straight ahead. Not all are successful.
I think that Baxter the Wonder Dog would be hopeless in this event. He is just too playful, not to mention incredibly attracted to any food.
Incidentally, almost anything funny can be made funnier by having Yakety Sax play in the background.
