drive them crazy for a few nights, then go out to them the third night, they tense up, they are going to run but you crouch down trying to keep them calm, then you show them how to use the laser pointer, it will take a while but they will understand. When you see they have understood stand up and put your hands on your hips and laugh like the jolly green giant. Then go back inside. Look back out the window. They are all just standing there looking at you. They look pissed.
