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.
Trivia: The woman who accidentally calls Burt Gummer (Michael Gross) "Mr. Goober" is actually played by Michael Gross' sister Mary. Like her brother, she's an actress who was a co-star on Saturday Night Live for several years in the 80's, and has done a smattering of film, television and voice-acting roles since.
