'Allo 'Allo - all 9 seasons streaming on Netflix

If you like British slapstick and if you (are old enough to have) enjoyed Hogan's Heroes give it a try. From IMDB:

In WW2 France, Rene Artois runs a small café where Resistance fighters, Gestapo men, German Army officers and escaped Allied POWs interact daily, ignorant of one another's true identity or presence, exasperating Rene.

The French are incompetent, the Germans are bumbling, and general silliness ensues.
