C'est pas parce qu'on a rien à dire qu'il faut fermer sa gueule... (1975)

Max and Riton, two petty crooks, work under Phano’s orders. After a botched robbery, Phano fires them, then calls them back to propose the biggest heist of the century: stealing the SNCF railway pension fund, kept in a safe beneath the Gare de l’Est in Paris. To get the money, they have to open the safe by making a hole through the adjoining wall from the station toilets. But to avoid arousing the suspicions of “Madame Pipi” (the toilet attendant), they have to take turns working in a series of disguises. In a van parked near the station, they stash numerous outfits and arrange to go down to the toilets at three-minute intervals, taking turns in the stall and patiently drilling a hole through the wall. Since the toilets are very busy, they constantly have to find ways to stop another customer from using the stall and spotting them. They return at night to finish the job and succeed in stealing the bundles of banknotes kept in the bank’s safe. As they leave the station at dawn with the suitcase containing the money, a police officer stops them for illegal parking outside the station. In the confusion, Max sets the suitcase down on the sidewalk, right beside other suitcases belonging to a school bus. After managing to get away from the officer, the three men have to follow the bus. Max manages to retrieve the suitcase, but then throws it, and it lands in a convertible before ending up aboard a train bound for Frankfurt am Main. Riton just manages to get the suitcase back. The three men then return with their loot. Phano fines his two henchmen for their various blunders and agrees to divide the money, but tells them it would be wiser to leave it untouched for six months so they won’t be caught and won’t fall victim to too abrupt a change in their standard of living. They gleefully realize that no one is on their trail and that Madame Pipi, interviewed by television crews, said she had seen and noticed nothing. Then Madame Pipi finds them in a restaurant and reveals that she has figured out they were behind the theft. She tells them about her past as a casino gambler, though she had to scale back her lifestyle. She proposes setting up a casino in which they would be her partners. The three accomplices have no choice but to agree. Her casino prospers, and after six months she tells them their original capital has quadrupled, and that it is time to divide it. Then, to their horror, they discover that their own safe has been emptied and that the method was the same as theirs: a hole made from the toilets. Ruined, they are seen sitting on a bench in Paris, where Madame Pipi, who has found work again in the toilets at Palais Royal station, reveals her plan for them to get back on their feet… by digging a hole to rob the Bank of France.
