I want to play a practical joke on my brother in order to scare him. What can I do?

You can put a plastic gila monster in his car or throw a teddy bear at him when he is not expecting it. If your brother has a fear of the dark, you can use black lights to create the illusion of glowing objects in his bedroom.
