The German 3
While we’re talking about Inglourious Basterds, we might as well point one detail that confused audiences until the secret was revealed moments later. In this scene, members of the Basterds team up with British Commando Archie Hicox to secretly meet up with undercover spy and beloved German actress Bridget von Hammersmark.
A Nazi colonel imposes on the “meeting between friends” before agreeing to back off and pay for a round for the group. When Archie holds up his index, middle, and ring fingers to show that they need three new glasses, the Colonel discovers who they really are. Apparently, real Germans symbolize the number three by holing up their thumb, index finger, and middle finger.
