IMDb goofed on a goof
Listed here as a "Goof" is Holland March's remark that Hitler was "only following orders," because Hitler gave orders, he didn't follow them. Of course; that was the joke! After March, who's always a few cards short of a deck, makes this claim, the others just give him a look of disbelief. (Cue the laugh).
I'm not crying, you fool, I'm laughing!
Hewwo.
