I really need help understanding why there is any correct answer to this question.

It says that one of John's friends must be lying, but how do we know that that is true since it is possible that John is mistaken and he might actually be unique among his friends.

Couldn't it be possible that John is the person everyone else is referring to?

    If the 40/40 guy was John, then John would know of someone like that... himself.
