This early Allen movie features some memorable concepts, such as Orgasmatron booths (and the related Intoxication orbs passed around at parties), confessional robots, bioengineered hydroponic vegetables (without any other part of the plant) such as hose-fed bananas as large as a canoe, and the cloning of vital organs and entire persons. Many things thought unhealthy in Monroe's time (including deep-fried fatty foods and smoking) are known by future scientists to be extremely good for you. Sometime between Monroe's time in the late 20th century and 2173 there was nuclear warfare, caused "when a man named Albert Shanker got hold of a nuclear device", and due to which much history is obscure or lost. 2173 historians show Monroe some surviving 20th century artifacts (such as a set of novelty wind-up chattering teeth and a crumpled photograph of Joseph Stalin) and ask for explanations. The historians have developed mistaken theories about Howard Cosell and Richard Nixon, which Miles doesn't have the heart to refute. Holding a photo: "This is Bela Lugosi. He was the mayor of New York". Regarding a photo of Nixon: "I'm not sure who he is, but every time he left the White House they counted the silverware".
