French Humour (Dumb as Fuck)
French comedy where intelligence is optional and commitment is mandatory. These movies are dumb on purpose, and they execute the dumbness with craftsmanship. Plus it's french so of course we'll make fun of it! If you’ve never laughed at something stupid with pride, welcome.

Honorable Mentions

A man whose entire personality is ‘surf’ despite living nowhere near surf. Pure idiocy. Somehow iconic.
Official synopsis
A wannabe surfer parties on the French Riviera while awaiting the perfect wave.

Prehistoric murder mystery with jokes so dumb they loop back to genius. French absurdity at full power.
