Trying to calm your brother down isn't an option. Telling him about the watch sounded even dumber. Pointing the watch, you turn the dial.
Almost instantly, Shaun's hysteria is silenced as he begins writhing and spasming on the floor. The transformation is on full display as you watch your brother's naked form.

You grab a new shirt and fix your pants, as Shaun's forehead pushes out, his jaw deminishes, and his nose flattens and enlarges.

Setting him down, you point the watch and turn the dial back. His body grows larger as you pull clothes from his closet. As Shaun becomes a monkey, you put a pair of underwear and pants on him. his body reaches a primate state as you get his shirt on. You race for the door as your brother hits caveman. You make it out and shut the door as Shaun returns to normal. You head downstair for breakfast, stashing the watch in your pocket.
A few minutes later, Shaun joins you. Your brother acts normal and goes about his daily buisness.
As you get in your car and drive to school, you think of who else you could use the watch on. You reach the school and wait impatiently through your first few classes. At lunch, you make your way to your first target...
