A bottle of Wisk laundry detergent is superimposed over the closing credits.
LeBeau claims to have baked Hogan's birthday cake, but when it's carried to the party, it is clearly too enormous to have been baked with any of the prisoners' tools.
When LeBeau arrives at camp after his meeting with Mama Bear, he has lipstick on his cheeks which was not there when he left the theater.
Klink: The German officer does not want his men to give him a party. All we want is respect!
Hogan: Who knows; someday you may even get it!
Klink: Are you insinuating that we are not distributing Red Cross packages?
Hogan: Oh, you're distributing 'em all right -- just be nice if the prisoners got 'em for a change.
Klink: Colonel Hogan, on what evidence do you back up that charge?
Hogan: Well, I would like you to show me where it says 'made in Germany' on this bar of peanut-brittle.
Newkirk: I'm afraid we've got a date with the firing squad.
Carter: Well, look at the bright side: at least we don't have to worry about what to get Colonel Hogan for his birthday.
Hochstetter: We are setting a trap.
Klink: Sir, are you questioning the security of Stalag 13?
Hochstetter: Klink, I question anything you are connected with. You may be caught in that trap.
