The Princess Bride!

Any other answer is... inconceivable

Monty Python Quest for the holy grail.

Every character, every scene

Monty Python and the Holy Grail

That would be the 1985 master piece Clue

Airplane.

Spaceballs?!?!

The Princess bride, no question!

Oh I'm sorry, did I break your concentration?

Aw man, I shot Marvin in the face.

You know what they call a quarter pounder in Paris?

And you will know that I am the Lord when I lay my vengeance upon you.

Hot Fuzz. Hands down.

Everyone's got guns round here. Like who? Farmers, Farmers mums.

Ghostbusters:

• Back off man - I’m a scientist 

• Listen! You smell something?

…and much much more

The Big Lewosky

Kung Pow Enter the fist.

My nipples look like milk duds

Galaxy Quest

Aliens

There is literally no competition. Every scene has at least 1 classic line. Aliens is also the gold standard reference used by all action movies since.

It's a dry heat

Nuke it from orbit

There goes our salvage guys

You got the duty, open that bag

Mostly

I have several ol' reliables:

Grandma's Boy: "high score? What's that mean?"

Snatch: "when you're in reverse, things tend to come from behind ya."

Tombstone: "i got two guns, one for each of ya."

Big Lebowski: "he's a good man Jeffrey. And thorough."

There's more, but those are probably my most quoted.

Super Troopers

From "The Snozzberries taste like Snozzberries!" to "BEARFUCKER! DO YOU NEED ASSISTANCE?!" almost every line in that movie is quotable and relevant to most situations.

• Blues Brothers
• Any Mel Brooks movie

Old School and Office Space

A lot of quotes from the Batman Dark Knight have become pretty common lingo or at least widely recognized, like "not the hero we deserve but the one we need" or "you either die a hero or live long enough to see yourself become the villain" or even "some people just want to watch the world burn" or "it's not about the money, it's about sending a message", maybe also popularizing the whole "immovable object vs unstoppable force" etc.

In French it s between Astérix mission Cleopatre and la cité de la peur
