What movie made you dying of laughter all the way through?

Ive watched a lot of comedies such as monty python and hot shots, scary movie, Airplaine!, etc.

Nowadays comedies just make me snore and bored. I need something funny to watch, one that is guaranteed to make me laugh. Not some movie wirh just tiny joke that make you chuckle for a second, i want to be on the floor.

I like movies that dont take themselves to serious. Or a movie where i dont really need to have seen another movie to understand the humor. Slapstick seems to work with this a lot.

Edit: thank you guys for the recommendations so far, although i will try to upvite as many as i can. i will compiling them into a letterboxd list. So far i have 18 :D Time to crack open a beer and sit back!

Edit edit: if any of you are interested in seeing the list, my dms are open
