Here's another one of those interesting questions from Opinionaided, however this is more of a riddle and brain teaser:

If Pinochio said, "My nose will grow now," what would happen?

My answer:
If Pinochio said that his nose will now grow, that would be considered a lie because his nose needs lies to grow. He can't just say that his nose will grow with his own prediction. This statement will result in his nose growing, however since his nose did grew, he essentially said the truth in a way. So I'm guessing that this double negative situation will cancel each other out, leaving Pinochio with a normal sized shnoz.
