On purge bébé (Baby's Laxative) is Jean Renoir's first sound film, based upon the play by Georges Feydeau.

It is a 1931 comedy about a supposedly unbreakable chamberpot and a constipated baby.

Mr. Follavoine seeks to sell unbreakable chamberpots to the French army.

In an attempt to close the deal, he invites Chouilloux, an influential official of the Ministry of hosts, for dinner to discuss putting his chamberpots on the market.

On 14 June 2016, American video-distribution company The Criterion Collection released On purge bébé, newly restored through a 4K digital transfer, as a bonus feature for the release of La Chienne on Blu-ray and DVD.
