Starring: Bob Crane, John Banner, Robert Clary, Werner Klemperer
That's No Lady, That's My Spy - S6-E17
Revealing mistake: When the men are in ranks for roll call, it's snowing heavily. Given the pitch of the barracks' roofs, there shouldn't be any snow sticking. Therefore, if looked at closely, it can be seen that the "snow" on the roofs is painted in place.
Klink for the Defense - S6-E19
Continuity mistake: General Burkhalter is eating Klink's dinner. When finished he places a metal cover over the plate. In the next shot the cover is lying on the table and there is extra food on the plate. (00:15:25)
Trivia: When Klink is begging Hogan to trade places with him for fear of assassination, he says to him something like."I want to live til 80...all my family has lived til 80." Werner Klemperer, who played Klink, passed away in 2000 aged 80.
Question: What exactly is the "cooler"?
Answer: It's a solitary cell. Steve McQueen, star of 'The Great Escape' is known as the 'Cooler King'.
