On Truth World, everyone must wear a truth collar which sends an electrical shock down a person's spine whenever he or she tells a lie. The size of the shock is proportionate to the size of the lie. It is illegal to remove the truth collars.
On Dinosaur World, dinosaurs never became extinct but humanity still evolved. San Francisco is a dinosaur reserve.
This episode's title is inspired by the Latin phrase "In Vino, Veritas" or in English "In Wine, Truth".
In the previous episode, Professor Arturo mentioned that "in vino veritas" meant "In wine there is truth." It was probably included so that more people would recognize the pun in this episode's name.
Quinn is off-screen for most of this episode so that Jerry O'Connell could film his role in Jerry Maguire (1996).
