Script Synopsis:A brief, illustrated lecture on digestion. Aburdist humor is the hallmark of this pseudo-scientific description of biting, chewing, swallowing, and digesting food. The on-screen narrator begins with teeth, "little sentinels" as he calls them, and the tongue. Then it's on to the stomach: he describes the stomach's workings as if it were an office or a factory. He uses an illustration of the side view of a human torso, with mouth, esophagus, and stomach visible, saying it's a photograph of a man with a visible digestive tract.
