Which movie makes you crack up not matter how many times you watched it ?
for me it’s White Chicks, lost the number of times i watched it, also recommend Tucker and Dale vs Evil.
SouthFresh, 
The House Bunny
easydnesto, National lampoons vacation and Christmas vacation, & Planes, Trains, and Automobiles.
SulaymanF, Zoolander.
MiddleWeigh, 
The first time I watched it in its entirety I was on shrooms. I fell asleep after it was over, and woke up to it playing from the beginning (comedy central late night replay) and I watched it again. Lol
protist, The Gods Must Be Crazy. There are legitimate critiques of its treatment of race since it takes place in apartheid Namibia and South Africa, but everyone in the movie seems to be having a great time and the physical comedy is top notch
wilberfan, 
Holy Grail. Animal House.
PanaX, Naked Gun 1-3
Airplane 1 and 2
Fatal Instinct
Hot Fuzz
The Other Guys
Chozo, Also came here to say Hot Fuzz! It's truly a masterclass in comedy.
Lapus, Anything by Mel Brooks

What can I say? A man of simple tastes.
housepanther, 
I still laugh at Shrek.
techgearwhips, Yes my very unpopular opinion is that white chicks is the funniest movie ever made. So many hilarious scenes. Also, Friday and Superbad always keep me in stitches.
JimmyDean, Hot Rod, Step Brothers, and Tropic Thunder are a few. I love Tucker & Dale vs Evil too
davemeech, Oh man, Hot Rod! Probably among the times I’ve laughed the hardest.
Hiuhokiguess, Pop Star is really good if you haven’t seen it.
Professorozone, My cousin Vinny.
HumorousJellyfish, 
“What is a yute? “Oh, excuse me, Your Honor,
Gets me every time 😂

What We Do In The Shadows
Tucker and Dale VS EvilAre the two that make me laugh no matter what.
Shoot Em Up too, but for different reasons.
cyberpunk007, +1 for Tucker and daie vs evil. What a great movie
FarraigePlaisteach, See No Evil, Hear No Evil
Grabbers
Kung Fury
Semi-Hemi-Demigod, 
Beavis & Butthead Do America is hilarious from start to finish
Lenny, When I re-watched it as an adult for the first time my mind was blown that Bruce Willis was in it.
This also reminds me I need to watch the new one.
Semi-Hemi-Demigod, The new one is good but not as good as the first
