He told me about a girl he knew who, while teaching English in Tokyo, had discovered that all of her Japanese adult students without exception believed, as a race distinct from everybody else in the world, they possessed an extra foot of intestine and were alone in being able to perceive every colour in the rainbow.

Even when this girl had insisted that these claims couldn’t be true – and attempted to prove it by numerous arguments and examples – her students had continued to believe that they were in the right and she the one being misled – a situation evidently astounding.

Of course, both of us had already had a couple of drinks at the time and so were in no position to judge.
