Factual error: Burt claims his watch updates its time "by connecting directly to the cesium clock in Colorado via ultrasonic frequency." Later the graboids home in on him by the ultrasonic sound emitted by his watch. Firstly, radio controlled watches update their time by receiving signals, but they don't emit any signals - the battery would be way too weak for two-way communication. Secondly, they work on radio waves, not sonic waves. Thirdly, if a hypothetical time transmitter did work on ultrasonics, the smallest distance between Colorado and Nevada is some 435 km (around 270 mi). An ultrasonic signal strong enough to reach that far would probably be deadly within a sizable range around the transmitter. (00:08:20)

Miguel: The BLM man gave me permission to kill anything that represented a danger to my cattle. El lobo, el coyote, and el Graboid.
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.
