If you're looking for a good laugh, look no further than some of the masters of French cinema:
Petit Nicolas

and it's sequel, Nicholas On Holiday

Looking further back, you can't go wrong with anything from the true master of French comedy, Jacques Tati. (Les Vacances de Monsieur Hulot and Trafic are probably my favourites though).
