As it happens, I was just reading the test standards for the FAA IR. It mentions that during the test, the examiner will cause a 'distraction' to assess your ability to concentrate on flying, and multi-task. I'm very curious as to what kind of things they might get up to - anyone have any examples?
There was also a case in the US some time ago about a snake that crawled out of a guy's instrument panel. A classic story; the pilot grabbed the snake and flew to destination with "one hand full of snake, and the other full of airplane". Upon landing "The pilot posed for photos with the snake before releasing it". Now that's one cool character!
