Continuity mistake: Hogan dumps a bucket of water on Barnes and Davis each, to make it look like they were the ones who hid in the tanker. They get big wet patches on their uniforms from it, but aren't completely wet through and through - which is to be expected, after all it's just a small bucket of water each. After the next cut however, they are completely soaked like they went swimming.
Trivia: During WW2 Robert Clary, who played Louis LeBeau, had been imprisoned at Drancy internment camp in France, and at Buchenwald Nazi concentration camp where he was tattooed with the number "A5714." He was the youngest of 14 children. Twelve members of his immediate family were sent to Auschwitz, and perished.

Question: When Hogan gives Klink $100 for the cuckoo clock, the bill handed over was a crisp American $100 note. How did Hogan get an American $100 note? At best, in this time period, he should only have Reich Marks. And how would he have 333 Marks, 33 pfennigs? Unless he had a side businesses going, this seems unlikely.
Answer: Werner Klemperer fled Nazi Germany as a teenager. His two conditions for taking the role of Colonel Klink were that he had to be a bumbling idiot and he always had to lose. It would then be a character mistake that if Hogan offers him a fresh American hundred-dollar bill, he's not going to ask questions, he's going to take the deal. The fact that he's Commandant and could just confiscate the money from Hogan would never occur to him because, again, he's a bumbling idiot who, by the actor's contract, always has to lose.
Chosen answer: Hogan and his men are running a spy ring out of the camp, they have access to supplies from outside. (In another episode, they have to convince a defecting German officer that they're legitimately working for the Allies by arranging a specific personal ad to run in the next day's London Times, so a new $100 bill is not beyond their capabilities).
Answer: Rightfully, Hogan should not have any money at all. POW were stripped of all cash they carried. The intention was to make escape more difficult. The fact that Hogan has what is the equivalent of a third of the price of a KdF-Wagen (You'd probably know it as a Volkswagen Beetle) in cash should rightfully make Klink more than a litle suspicious.
Read my answers above. Klink is an idiot and would never think to confiscate the money.
Answer: It's a comedy, not a documentary.

Perhaps it was counterfeit. There are numerous episodes where they deal in counterfeit monies.
