Long ago I had a Chihuahua and we were good friends. Occasionally while fixing food in the kitchen, I would toss part of a hot dog down to him and he'd wolf it down, naturally.

I had bought some "Smart Dogs" to try them out and they were...yuck. They looked identical to real thing though, so I tossed an entire one down to him.

In slow motion, you could see his greedy little face light up as the counterfeit dog soared in his direction. He caught it flawlessly like a classic Tom Brady floater landing squarely into his receiver's hands.

Then, a pause. Then, simultaneously, his little mouth opened, his tail stopped wagging, and the "dog" fell to the floor. He gave the floor-dog a second sniff to make sure his mind wasn't playing tricks on him, then looked back up at me with treacherous zeal.
