A small white dog stands on its hind legs on a green mat in a kitchen, repeatedly jumping up to bat at a hammer suspended by a string from a counter, causing the hammer to swing back and forth. The scene then cuts to a close-up of a Rube Goldberg-style contraption on a wooden board, where a metal ball rolls down a ramp, hits a green tube, and triggers a sequence that causes a pencil to be knocked forward.
