My brother and I love the book Lizard Music by Daniel Pinkwater. I mean, we love all his stuff, but LM especially.

For several years, I've wanted to make him his own lizard watch. In the story, the lizards wear plain rocks as watches. When someone asks them the time, they know exactly what time it is. Later on we learn that they are just guessing the time.

So, here is the watch. He'll pee himself laughing.
