Pick up a dog so it can see things from your point of view
(Amusement Potential: 3-5 minutes)
Think about it: your dog has only seen the house from a viewpoint from 6" to 2' high (15 to 60 cm for all you metric fans). It's never seen the tops of counters, what you keep on your desk, the tops of shelves, etc. Try looking at things from its point of view, too.

Push your eyes for interesting light show
(Amusement Potential: 1-5 minutes)
