Heil Klink - S2-E22
Continuity mistake: In the beginning, Carter and Newkirk are wiring in the explosives. As they run the spool of wire, first it unrolls clockwise, then counter clockwise between shots.
Heil Klink - S2-E22
Continuity mistake: The light switch for Klink's office is usually located right next to the door, with the wires going up toward the ceiling. This time, the switch is missing.
Heil Klink - S2-E22
Revealing mistake: After Browner gets out of the staff car and is going inside, as the camera pans to the left following him, you see the Desilu Studios water tower.
Heil Klink - S2-E22
Continuity mistake: After the phone call leading Klink to believe Hitler is coming by, he stands and goes to Hogan. As he stands over Hogan, he is gesturing with his left hand. When the camera angle changes, he's using his right hand.
Heil Klink - S2-E22
Continuity mistake: As Brauner, dressed as Shultz, gets into the staff car, he has no glasses on, as Shultz does not routinely wear them. After the shot cuts to Shultz and back to Brauner, and as the car pulls away, you see Brauner with horn rimmed glasses suddenly on.
Everyone Has a Brother-in-Law - S2-E23
Factual error: Schulz repeatedly calls Klink's adjutant "Kapitän." In the German armed forces the rank Kapitän only exists in the Navy, the German equivalent for the American rank of Captain (which is obviously meant here) is Hauptmann or Stabshauptmann.
Everyone Has a Brother-in-Law - S2-E23
Other mistake: When the boys are listening on the coffee pot, the red light to indicate power is not lit.
Everyone Has a Brother-in-Law - S2-E23
Continuity mistake: Hogan is reading the note from the underground on the clipboard that Newkirk brought in. When done reading, Hogan is holding the board at waist height. In the close up, it's suddenly chest height.
Continuity mistake: When Klink is talking to Schultz, his monocle is in before he bends down, missing when he's looking at Schultz, and back when he straightens up.
Continuity mistake: As Schultz is going to get checked out, Hogan and the boys stop him, and Hogan feels Schultz's neck. Schultz's arms are by his sides, then after the angle change, they're by his hips. Also, there's two men walking behind the group that weren't there a second before.
Continuity mistake: When Klink is talking with the doctor, he sits while reading the report. One moment, he's holding the folder, the next, his hands are folded without having dropped the folder.
Continuity mistake: As Schultz comes in, Klink has his left hand on his forehead. As Schultz is talking, Klink starts to raise his head, his hand very close to his forehead. When the camera cuts to a close up, his hand is below chin level.
The Most Escape-Proof Camp I've Ever Escaped From - S2-E26
Continuity mistake: In the beginning, Carter's hair has been buzz cut. A few minutes later, it's back to regular length.
Continuity mistake: When Kinch raises the binoculars to look at The Tower, the neck strap is crossed in an "X" on his chest. When he puts them down, the strap is straightened.
Colonel Klink's Secret Weapon - S2-E28
Continuity mistake: During the inspector general's visit, Le Beau and Newark fall out with switched hats (i.e. Newark is wearing Le Beau's red hat and vice versa). In the next shot when in formation, they are wearing their own hats. (00:21:00 - 00:22:00)
Colonel Klink's Secret Weapon - S2-E28
Continuity mistake: When Franks turns in his report to be signed, Klink said "Kommandant's efficiency reports are six weeks behind." When he talks to Hogan later to get rid of Franks, he said the reports were six months behind.
The Top Secret Top Coat - S2-E29
Continuity mistake: When Hogan and company are getting ready to listen to the sock from "Aunt Alice" they plug the coffee pot up to their recorder. As they do so, the light that indicates power is lit up, but then Lebeau plugs in the power cord.
The Top Secret Top Coat - S2-E29
Factual error: In Klink's quarters, there's an (obviously fake) banana in the fruit bowl. Bananas were luxury items in Europe in the 1940s, and certainly so in war-torn Germany. The majority of Germans didn't have access to exotic fruit until the 1960s, and fake fruit of this type wasn't available then either.
