Earl: Are you now, or have you ever been an herbivore?
This alludes to what was known as the "$64 question", "Are you now, or have you ever been a member of the communist party of the United States?", asked by the House Un-American Activities Committee of suspected communist sympathizers. The committee was active from 1938-1975.

Martin Luther King: Robbie's speech about how he "dreams about Dinosaurs being judged not by the food they eat, but instead by their character" is derived off of Martin Luther King Jr. speech.
