Latin Abbreviations and the Mob

Perhaps you remember this linguistic exchange (here slightly sanitized) between Ray "Bones" Barboni and Chili Palmer (played by John Travolta) in the movie Get Shorty (1995):

Barboni: Let me explain something to you. Momo is dead. Which means that everything he had now belongs to Jimmy Cap, including you. Which also means, that when I speak, I speak for Jimmy. E.g., from now on, you start showing me the proper . . . respect.

Chili Palmer: "E.g." means "for example." What I think you want to say is "I.e."

Barboni: B---t! That's short for "ergo."

Chili Palmer: Ask your man.

Bodyguard: To the best of my knowledge, "e.g." means "for example."

Barboni: E.g., i.e., . . . the point is this: when I say "jump," you say "OK," okay?

In fact, the bodyguard is correct: the Latin abbreviation "i.e." means "that is"; "e.g." means "for example."

Movie mobsters aren't the only ones who are confused by Latin abbreviations. N.B. (or "a word to the wiseguy"): if you'd like a quick refresher, check out Commonly Confused Latin Abbreviations in English.
