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.
The Red Stapler: Quite a few items from the movie (like the Wally World eggnog glasses) are popular Christmas items and Clark's Blackhawks jersey (seen in the "Shitter was full!" scene) is popular with Chicago Blackhawks fans.
Vindicated by History: Although the film was well-received when it was released, in the years since its popularity has grown. It's now considered a classic Christmas film similar to A Christmas Story and many families have made watching it an annual holiday tradition.
