Why do you think Harry and Lloyd were mentally handicapped?
The Suntan Team scene?
Same here. A friend whose tastes I seldom agree with, had to practically beg me to watch PWBA with him. I’m SO glad I grudgingly gave in, for the reasons you mentioned.
I have it in DVD, my kids liked it when they were young.
You havent met many workers in the fast food or any minimum wage industry, have you? 
Well, what is the title of the film? How do they act? If not clinically handicapped, they were below average. These are not guys who are average and do dumb things- they are dumb dudes. They supposedly have IQs of 70.
Where was Dumb and Dumber filmed?.
IQ of 75 is the cut-off-

While a specific full-scale IQ test score is no longer required for diagnosis, standardized testing is used as part of diagnosing the condition. A full-scale IQ score of around 70 to 75 indicates a significant limitation in intellectual functioning.2
Of course, simply IQ is no longer the end all and be all, true. They are functioning- sorta.
But they could easily get on SSI.
If you think laughing evilly is good acting, it’s hard to surpass Battlefield Earth.
I’ve known lots of people of average intelligence who were dumb as a stick. Many held managerial positions, so occupation doesn’t seem to matter. Elected officials are the worst.
Nobody’s given romantic comedies any love, so I’ll cop to adoring A Christmas Prince, a schmaltzy Netflix movie that manages to shoehorn in every Hallmark movie trope in existence. They play it 100% straight while dishing out cliche after cliche. It’s hilarious. They had to know what they were doing. They had to know.
It would and probably does make a good drinking game.
Spaced Invaders. An alien ship from Mars, a B-team, pick up a broadcast from Earth of a radio station rebroadcasting Orson Welles’ War of the Worlds of 1938. They decide to land on earth so as to not miss out on the invasion they think is happening. They land on Halloween, so everyone thinks they’re trick-or-treating.
Then things get weird.
Horrible movie. I laughed all the way through it. One alien ends up doing a Jack Nicholson impression.
Just found out that the earthling daughter was played by Lex of Jurassic Park fame.
There’s a difference between “smart” and “wise.”
You know there are a lot of minimum wage workers with a high level of education, right?
Me, too, but they’re a lot harder to find than the Chan ones.
You don’t need to be of average intelligence to work and drive. “Average” isn’t the minimum level needed to function in society.
Postal, directed, co-produced and co-written by Uwe Boll. Based on the awful (but still somehow fun) Postal video games. Cost $15 mil to make and earned $146k at the box office. It earned Boll a Golden Raspberry for Worst Director. It’s available to watch for free online, which is a fair price.
“Infantile, irreverent and boorish to the max, Postal explodes with bad attitude and lousy filmmaking.” - 0.5 of 5 stars - New York Times
I adore this movie, too. When it cane out on DVD a few years ago I bought it. Return of the Killer Tomatoes as well.
My vote is for The Green Slime, the inspiration for the board game :The Awful Green Things From Outer Space by TSR and Steve Jackson Games, What looks like green soap bubbles invade a tear in a astronaut’s spacesuit. Eventually they grow in into six-foot tall paper mache monsters which infiltrate the space ship. Unintentional hilarity insues.
I remember that on TV when I was a kid. It was scary then, now I probably would laugh.
Hyperspace. This one is borderline on the “fun” part. Basically Imperial Stormtroopers (or a facsimile thereof) along with their evil dark overlord (not based on Darth Vader, no, never, never) mistakenly land on Earth. They’re searching for stolen plans and they think Chris Eliot and Paula Poundstone have hidden them in her ShopVac. “Clever of you to hide them in your droid, princess!” The funny runs out about a third of the way through.
Seems Corvette Summer has a place on this list.
The Cheech & Chong movies maybe? At least the first 3. Other than their talked about stoner humor, there were some pretty good ( and clever ) sight and sound gags as well.
