Cats have nine tails. No! Really!

I am going to prove to you that cats have nine tails. Right here, right now. Ready?

Do you agree with this statement:
No cat has eight tails.
(Your answer is yes)

Now, imagine that I show you two boxes. Box one has a cat, box two has no cat. Ok, how many more tails does box one have? (You answer one)

Using the facts, that one cat has one more tail than no cat and that no cat has eight tails. One more tail than no cat is in other words, nine tails. Then using logic, cats have nine tails.

Freaky, huh?
