Classic Bait And Stitch

Daily Mail does a segment called Me and my operation, wherein a patient describes what surgery they had done, and then the surgeon describes what surgery they did. This way the patient can use words like "gullet" and phrases like "I used to eat a couple curries every week," and the doctor can say things like "involves cracking the chest open" and "the oesophagus is a tube," and no one seems condescending at all. (Oesophagus is the British esophagus. It's a tube.) Then, at the end, you find out the patient is actually a doctor trying to pretend like he doesn't really understand. Also the doctor is an airline pilot trying to pretend like he does understand. But then they just laugh and are glad everything went okay.
