'Allo 'Allo! S01E02 - Pigeon Post

The Colonel & the Captain mull over their situation and decide they should probably hand over René and the painting to the Gestapo in order to get rid of Herr Flick. But René convinces them that they could hand over a forged copy of the painting instead (with the assistance of a conveniently-located forger), and gets them to lend their uniforms to the escaping British officers so the Brits can take the painting to England to be forged.
