Clue (1985) starring Christopher Lloyd, Tim Curry, Madeline Kahn, Eileen Brennan, Michael McKean, Martin Mull, and Leslie Ann Warren. A murder mystery comedy based on the board game of the same name.

Have you seen Airplane! Or The Naked Gun series? Those have some hilarious moments..

“Looks like I picked the wrong week to stop sniffin’ glue!”

Big Trouble in Little China! Great 80's action comedy with Kurt Russell and Kim Cattrall. Drink every time Kurt's character asks a question. Lmao.

Its definitely one of my favourite movies ever. Very chill and funny.

The Life of Brian - no idea if it is "uncommon" but I haven't seen it being mentioned anywhere in ages. It has a weird and macabre but enjoyable mix of super dry English humor, whacky sillyness and actual satire, while still managing to tell a coherent story.

The Hudsucker Proxy.

You know, for the kids.

"Orgazmo"? Think it's South Park creator's first movie together. Story of a Mormon who goes into porn to pay for his dream wedding.

"Toc toc" is a funny Spanish comedy. Revolves around a group of people waiting in a doctor's office and each one has a different type of OCD. Think it might work on a subtitle level too, but definitely funnier if you understand Spanish.

"Carnage". Two sets of parents try to resolve an altercation between their children, and it just slowly descends into madness.

Death to Smoochy.

Robin Williams plays an established children's entertainer and Edward Norton's character is an up-and-coming performer.

Better Off Dead.

I would say black dynamite or tucker and Dale vs evil

Four Lions

I rarely see Mystery Men mentioned these days. Don't even see memes from it anymore.

Tucker and Dale Vs Evil is one of my favorites, might not be quite uncommon but people tend not to know it when I bring it up.

Office Space, not exactly uncommon but not talked about that much these days and still relevant.

Kung Pao: Enter The Fist

Black dynamite is amazingly funny. A satirical 70s action/crime movie

Btw its written by michael jai white. And he is making a new movie.. "outlaw johnny black" where he plays a cowboy/gunslinger. I am looking forward to it

Quick Change. It's full of big stars (Bill Murray, Randy Quaid, Geena Davis, Jason Roberts) but I never hear people talk about it. I find it pretty funny.

Balls Out: Gary The Tennis Coach (best film with Seann William Scott as lead imo)

Dirty Work

Palm Springs on Hulu (flew under the radar for most people I know)

Vice Principals (TV show)

Almost Heros

Hamlet 2. There are some problematic things in it, that haven’t aged so great, but it is otherwise amazingly funny.

It’s a mad mad mad mad world.

Is Brain Candy uncommon?

don't know how good the dub is, but Lammbock is the best stoner movie i've ever seen.

Tampopo is pretty great, and, I feel, pretty obscure as well.

Without A Clue

Enjoyable take on Sherlock Holmes with Ben Kingsley as Watson, who is the real genius, but creates a character for his stories, and hires an actor to play Sherlock Holmes, played by Michael Cain. Never got the attention it should have, with two fabulous actors and a clever script, plus music by Henry Mancini.

It’s one of those movies that we watch again and again.

A Dog's Breakfast

Bowfinger

Surf Ninjas

The Slammin' Salmon

Crimewave. Many have not heard of it. It's problematic in parts.

Writers: Coen Brothers. Director: Sam Raimi.

Yep.

Kingpin

I don’t know that it’s all that obscure, but with Halloween coming up you should see Tucker and Dale vs Evil if you haven’t already. It’s a role reversal of the teens in the woods trope. Two redneck buddies (Tyler Labine and Alan Tudyk) are renovating a hunting cabin when they save a young woman who knocks herself unconscious in the lake. Her friends think the rednecks are creepy killers and proceed to attack the two in an attempt to save their friend. The teens end up accidentally killings themselves one by one all over the rednecks’ property scaring the hell out of everyone involved, and that’s just the beginning.

"Who is killing the great chefs of Europe" If you ever want to see great European humor akin to monty python's stuff this would be one! Grab some bugles cause it's a good one

Hank and Mike.

In a world where being an Easter bunny is a corporate gig. Two bunnies find themselves suddenly unemployed and must try their hand at other jobs. It's live action with people in bunny suits. Alot more entertaining than it sounds and full of funny debauchery.

The Wizard of Speed and Time (Mike Jittlov).
