If someone were to call them selves a liar, but that would make it true so it wasn't a lie hit the the statement was a lie so they are. 

This is like the paradox "This statement is false"

Like the Pinocchio one 'my nose will now grow'

They could still be a liar. The Pinoccohio paradox works however. As he has a direct response to every lie he tells.
