Gee, I just don't watch nearly as many foreign comedies as dramas, or I don't like much the ones I do. Some that are at least a bit comedic and I'd highly recommend:
Son of the Bride (Argentina)
Mostly Martha (don't be fooled by the fact that this was remade into a presumably horrible American movie with Catherine Zeta Jones) (Germany)
Elling (Norway)
Il Postino (Italy)
Monsoon Wedding (India)
Eat Drink Man Woman (Taiwan)
Goodbye, Lenin! (Germany)
Delicatessen (France) (probably not good unless you like dark comedies)
My Life as a Dog (Sweden)
Persepolis (France, animated)
The Triplets of Belleville (France, animated, musical)
The Wedding Banquet (Taiwan)
Women on the Verge of a Nervous Breakdown (Spain)
My second tier would include Italian for Beginners, Mediterraneo, L'Auberge Espanole, Late Marriage, The Dinner Game, Ma Vie En Rose (not the one about Edith Piaf), Tie Me Up! Tie Me Down!, and Kitchen Stories.
