Standing outside the bathroom at an airport, waiting call the cops on the janitor if they go in the "wrong" bathroom. No, seriously, that isn't on the list of exceptions in that bill.

I've never had to say it out loud, but if I did, I'd pronounce it "core duh len" and so help me god if anyone tried to correct me, I'd switch to painstakingly pronouncing every individual vowel sound with a slight twang, and continue saying that way until the day I die. "Co-ee-oor duh a-lee-nee."
