It’s a beautiful evening at a popular tourist destination. Many of the tourists, including a (medical) doctor, have decided to dine in a fine restaurant. Amid the dinner, somebody starts forcefully coughing in the table next to the doctor’s. The doctor gets up, goes to the adjacent table and sees a man with a big, half-eaten steak in front of him, coughing like crazy. The doctor asks the entourage:
–Is he choking?!
–Of course he isn’t [joking], one of the people said while patting the coughing man on the back.
–Oh, that’s good, he had me worried for a moment.
Or maybe it went like this:
–Is he joking?!
–Well what does it look like, of course he is [choking]!
–Oh, thank God, I thought it was serious.
Well, actually joke [dʒoʊk] is pronounced differently from choke [t͡ʃəʊk] – but I don’t think I would hear, let alone pronounce, the difference.
