Have you ever been presented with one of those cards that says, “If you want to know how to keep an idiot busy, turn over this card”? This video shows the canine version of the same concept.

Apparently this guy realized that his dog likes to chase light beams, then got the bright idea to put a flashlight on his dog’s collar. It’s easy to figure out what happens when he turns it on, but it’s fun to watch all the same.

This brings to mind the same question I’ve always had when I see a dog chasing a car: What is he going to do with it if he catches it?
