Burt: A lifetime of preparation, and I end up a refugee?
Trivia: The scene where a kid accidentally refers to a Graboid as a "Tremor" was a bit of an inside joke, as it's a common misconception among people who aren't fans of the series that the monsters are called "Tremors." It's always slightly annoyed the cast and crew, so they added the scene as a goof.
