I know people who do that, and I don't get it. If you tell you that I saw a cat sitting on a cow today, why would you doubt it? There is no way in which believing or not believing it will influence you in any way, so whatever.
I don't get where the fascination is in doing that. Everyone can do it. Actually my 4 year old sister does that all the time.
But she sucks really bad at it.
Ok I guess you can out-lie my 4 year old sister.
