Hoganheim A Funny Thing Happened on the Way to London - Hogan's Heroes Season 3 Episode 5

An old friend of Colonel Hogan's has appeared at Stalag 13, and Klink seems eager for Hogan to talk to him. Little do they know that the Germans are preparing an impostor, surgically altered to look like Hogan's friend, and convincing Colonel Hogan that he is who he says he is will be the final test of his masquerade. Once that's done, his mission is a big one: assassinate Winston Churchill.
