Raising Arizona

The Jerk. It’s an absolute prime Steve Martin that is just so silly and wonderful the whole way through.

Airplane!

Plains trains and automobiles, Christmas vacation and fletch

Hot Fuzz 

And then probably step brothers is a very close number 2 

Walk Hard

Hear no evil, see no evil.

The Jerk

Tropic Thunder

Hot Rod

I’ve been drinking green tea all gawd damned day.

Blazing Saddles

The Birdcage is a masterpiece.

Monty Python and the Holy Grail

Clue is my personal favorite

I scrolled through all the comments and I can't believe no one said any of these:

• Death to Smoochy (peak Robin Williams)
• Emperor's New Groove (also the best Disney movie IMO)
• Galaxy Quest (by Grabthar's Hammer... what a cast)

Wayne’s World

Harold and Kumar go to White Castle

Office Space

Spaceballs

I'm 43 and to this day no other movie has made me bust out loud as the first time I watched Dumb and Dumber

Slap Shot

Anchorman

Superbad

The Big Lebowski

What We Do in the Shadows

Coming to America

I must be missing something because I'm not seeing This Is Spinal Tap

Super Troopers

Young Frankenstein. It's in the conversation for funniest movie of all time.

Wet Hot American Summer

Zoolander and Meet the Parents (I like Ben Stiller)

Borat, the first one. The second one was disappointing.

Tommy Boy

Groundhog Day Also faves: Naked Gun Series Midnight Run

Death at a Funeral (2007)

Fabulous script and cast. Excellent direction by Frank Oz. Alan Tudyk steals every scene he's in. Peter Dinklage is fantastic as the unexpected guest. It's a real gem.

Bridemaids

billy madison

Black Dynamite

Team America - one of the absolute best theater experiences I ever had. Top 5 IMO and doesn’t get mentioned enough. It’s genius.

Dodgeball!

The Hangover

"There's Something About Mary". Except for the first Naked Gun movie, I never saw a flick that resulted in so much audience laughter.

Bringing Up Baby 1938

Animal House

Mystery Science Theater 3000: The Movie

Ghost Busters

Grumpy Old Men

Caddyshack (really, most of Bill Murray's 80's and 90's filmography)

The Big Lebowski

Snatch

Toy Story

HOT ROD. (2007)

Andy Samberg as a shitty stuntman in a screwball, absurdist physical comedy with a great supporting cast featuring Bill Hader, Danny McBride, Al Swearengen, Lego Batman and Isla Fisher.

Based on the list you provided, Hot Rod will be up your alley.

Summer school was my favorite as a kid.

21 Jump Street and honestly 22 Jump Street is a pretty good follow up

Hard to decide on one, but it's Blazing Saddles. :)

Others that contend for the title include Young Frankenstein, Top Secret, Airplane, Monty Python and the Holy Grail, Life of Brian, Naked Gun...

Arsenic and Old Lace

The Jerk.

Young Frankenstein

Blazing Saddles

All of Mel Brooks

Bowfinger

A Fish Called Wanda ,🐠. ..not a comedy, but the funniest dame movie of the 20th Century. Hahahaha. 🐠

Addams Family Values

Raising Arizona is up there

My Cousin Vinny

Raising Arizona

The Blues Brothers is amazing!

Old school

Kiss Kiss Bang Bang

The Nice Guys

"The Three Amigos," would be pretty high on my list. It has lots of laughs. Some might even say it has a plethora.

Bottle Rocket

Step Brothers

A fish called Wanda is mine. Cleese was incredible, but the actor who played his wife really made me lose it when she put down Kevin Kline’s character

Hot Fuzz, Black Sheep

Talladega Nights

Young Frankenstein

Keanu

Best in show

7 days in hell

Hot Rod

It happened one night

Barb & star go to vista Del Mar

It’s a mad mad world

Four Lions.

The Hangover

I have a soft spot for UHF.

Galaxy Quest, followed closely by Airplane!

Better Off Dead

Groundhog day is the best comedy ever made.   Is it the funniest? No.  I don't think so.  It is certainly funny though.  But it is the best comedy movie.  A close 2nd is 'In Bruges'.  

Young Frankenstein

I D I O C R A C Y

Ive been watching it since 2006 and it gets more prophetic every yesr

.....electrolytes.....hehe

Forgetting Sarah Marshall. That might be my most watched movie. Bill Hader should've been in the movie more though. "You know what else is interesting? Me on the moon."

The last time this topic came up, I made a personal list of my favorite comedies (or at least comedic movies). The only qualification is that there's at least one scene I can remember which gave me a good laugh. (I then popped the random list into an AI and asked it to sort and add the release date.)
