Well, if they have such a great time arguing with other people, why don't they leave you alone and go to Monty Python's Argument Clinic instead? There they'll find highly qualified, experienced professionals who will be happy to argue with them. The only difference is that they'll have to pay.
If you want to practise English short answers ('Yes, it is!' 'No, it isn't!'), visit this surrealistic clinic too. Watch the video below and you'll hear countless examples of them. For further practice, you can also try pausing the video in the middle of an argument: can you guess what's the next short answer they're going to use in order to keep the argument going? Did you get them right?
