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.
Acceptable Ethnic Targets: Mr. Wang, Al's East Asian guest. But that's minor compared what the film does to WASPs and Irish-Americans.
Czervik: I hear this place is restricted Wang, so don't tell them you're Jewish.
Dude, Not Funny!: Bill Murray's eccentric groundskeeper, reportedly based on a real man who suffered from serious mental problems, might not seem as funny to people with relatives who suffer from Autism and/or other mental health problems.
Memetic Mutation: Every golf-related scene and quote has been hijacked and parodied by sports channels. Actually, this movie's created so many memes that a Saturday Night Live sketch in the late 1990s had Bill Murray, the night's guest host, present a Parody Commercial for the book The Quotable Caddyshack. The ad argues that if you're a guy, knowing Caddyshack memes is vital to relating to other guys.
"Now, how 'bout a Fresca?"
Romantic Plot Tumor: Danny has a girlfriend. Oh, maybe she's pregnant! She isn't? OK, forget it.
Sequelitis: The second movie came out almost a decade later, only brings back one original cast member (Chevy Chase) and Suspiciously Similar Substitutes of the first movie's main characters who hit the same beats story-wise.
Strawman Has a Point: Smails is unquestionably being a dick when he tells Danny "The world needs ditch-diggers, too!", but it turns out, yeah; there's really nothing wrong with working blue-collar (and in Real Life, the pay is usually pretty good).
Vindicated by History: Only an average success at release, has gone on to become one of the most memorable comedies of all time.
