Announcer
Number 16: The hand.
Interviewer
Good evening. I have with me in the studio tonight Mr Norman St John Polevaulter, who for the past few years has been contradicting people. Mr Polevaulter, why do you contradict people?
Norman
I dont. [1]
Interviewer
You told me you did!

[1] This is, naturally, a lie, but paradoxically if it were true he could not say so without contradicting the interviewer and thus making it false.
