Duck Soup.

Fleeing a group of forest rangers, who are rounding up tramps to serve as firefighters, they take refuge in a mansion. The owner has gone on vacation and the servants are away, so Hardy pretends to be the owner and offers to rent the house to an English couple. Hardy gets Laurel to pose as the maid. Unfortunately, the owner returns and tells the would-be renters that he owns the house; Laurel and Hardy then flee again and are caught by the rangers and forced to fight wildfires.
