Counting Differences on One Hand: Numerical hand gestures across cultures
Spoiler Alert! In our prolonged Oscar fever, this post is inspired by another 2009 Best Picture Nominee, Inglorious Bastards. If you haven’t seen the film, and would like to, please be advised that plot elements are contained below. 
In Quentin Tarantino’s 2009 WWII hit Inglorious Bastards, one of Lt. Aldo Raine’s soldiers is impersonating a German soldier successfully at a bar with his excellent command of the language, that is, until he raises his hand to order glasses. His words are perfect German; his hand gesture, however, is not, and gives away his cover to a German officer.
