Carter mentions that he was a 'decorator' before the war. In another episode, Carter mentions that he ran a drugstore.
UPDATE: This is not correct. Carter does not mention this. Hogan tells Klink that Carter was a decorator. He didn't have to be telling the truth to Klink.

This has the first use of the phrase 'Court-martialled, shot, and sent to the Russian Front' in the series. Klink says it when making a phone call telling sentry post 9 to tell the motorcycle messenger not to go to Dusseldorf.
When Klink exits his office before the bridge blows up, he says he will smash all the Bing Crosby records as well as the Tommy Dorsey records. Bing Crosby Productions were producers of the Hogan's Heroes TV series.
One of the graffito painted on the armory reads "Hess Is a Mess." Rudolf Hess was Nazi Germany's Deputy Fuehrer, and he was a mess. In May 1941, purely on his own initiative, he flew alone to the British Isles in an attempt to broker a peace between Britain and Germany. This enraged Hitler, who denounced him publicly and privately ordered him killed if he ever returned to Germany. The British interned him for the duration. After the war, Hess was tried as a war criminal and was imprisoned in Berlin's Spandau Prison for the rest of his life; after 1966, he was the sole prisoner left in Spandau. Having made a number of suicide attempts throughout his life, Rudolf Hess was finally successful in 1987, aged 93. Hess was a mess.
