The Sausage in the Trousers (S04E05)

René's mother-in-law's wireless radio remains without batteries, prompting Michelle to hatch a ridiculous plan: she enlists René and Yvette to power it using a bicycle generator until the stolen batteries from a German miniature submarine arrive. Meanwhile, the Lieutenant finishes replicating the paintings, The Fallen Madonna and a Van Gogh, and delivers them disguised as sausages. Additional sausages come in—genuine ones from Captain Bertorelli, submarine batteries from Leclerc, and explosives from Officer Crabtree—resulting in a chaotic mix-up in the trousers of the German officers!
