Here Jack displays three basic responses to stimuli: 1) extend tongue, a la Michael Jordan, for no apparent reason; 2) regard moving and/or noisy object as something that may be of mild, passing interest (also known as the "meh" response); or 3) feign shock and delight at the sheer excitment of the thing, in this case an octopus with only five legs (we call it a "quintupus").
