These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fridge Brilliance: When Reese tapes a kilo of Colombian bam-bam under Ricky's car (actually a bag of Lucky Charms cereal). What do some call the "War on Drugs"? Prohibition II. How did NASCAR get started? Running moonshine in Prohibition I. Ferrel and the filmmakers were explicitly calling bullshit on the War on Drugs!
Fridge Horror: While Granny is whipping Walker and Texas Ranger into shape, she asks "How many times are you going to throw me the radio when I'm in the bathtub?" Considering that doing that can kill someone, those kids seem downright evil.
Hilarious in Hindsight: Ricky Bobby's downfall and subsequent effort to rebuild his driving reputation, after Kurt Busch went through a two year stretch like this after Roger Penske fired him at the end of 2011 Sprint Cup season for outbursts. During this time, Busch lampshaded it by driving Ricky Bobby-based cars at Talladega (a "ME" Cougar car in May 2012 for Phoenix Racing and a Wonder Bread car in 2013 for Furniture Row Racing).
Memetic Mutation: "Shake and bake!" In fact it has been heard on actual Sprint Cup drivers' radio communications and also has been used by the TV commentator teams.
And, for a while, "the best Playstation 3 game on the market." Explanation Early Playstation 3s were bundled with a Blu-Ray disc of the movie.
