Napoleon Dynamite: [Reading current event to class.] Last week, Japanese scientists "explaced" - placed explosive detonators at the bottom of Lake Loch Ness... To blow Nessie out of the water... Sir Curt Godfrey of the Nessie Alliance. Summoned the help of Scotland's local wizards to cast a protective spell over the lake and its local residents. And all those who seek for the peaceful existence of our underwater ally.
Trivia: After Uncle Rico throws the steak at Napoleon when he's riding his bike, Rico sits back down on the porch and you can see him discreetly spit something into his hand and put it down. According to the DVD commentary, this was the bite of steak he was eating, because Jon Gries, who played Uncle Rico, didn't eat red meat. Between shots he spat out all the many bites of steak his character had to eat.
