The scene.. A college lecture hall

"Good morning, class. Today, in Bankrobbing in Obscure Languages 101, we'll be learning how to hold up a bank. That's right, ladies and gentleman, today's lesson contains top secret knowledge -- how to tell a bank's customers to reach for the sky, and how to tell the tellers to give you all their money. And "Don't even think about sounding the alarm", another good phrase."

The professor walks up to the blackboard and begins writing.

  • "Nobody Move! -- Nemo Agitate!"
  • "Put your hands in the air! -- Manus tuas in aeri pone!"
  • "This is a holdup! -- Hic furtum est"
  • "You, give me all the money -- Tu, omnem pecuniae da"
  • "And don't even think about sounding the alarm... -- Classicum canendum nole contui quidem"

The teacher puts the chalk down and turns to face the class. "Now, remember, almost nobody will understand what you're saying, so just shout and wave your gun a lot, they'll probably get the idea. Would anyone like to know how to hold up a bank in pig-latin now..?"

Note: Tenses of verbs and suffixes of nouns may vary.
Crux was a little perturbed about how poor my Latin was, so I changed it.
That's right, all the Latin in this writeup is Crux's.. so hats off to 'im!
