Some questions to think about...

If you choke a smurf what colour does it turn?

How do you tell when you've run out of invisible ink?

If practice makes perfect, and nobody's perfect, why practice?

If swimming is so good for your figure, why are whales so fat?

If you are born again, do you get two belly buttons?

If you ate pasta and then antipasta would you still be hungry?

What happens if you get scared half to death twice?

If Barbie is so popular, why do you have to buy her friends?

And finally... If a tree falls down in a forest, do the other trees laugh at it?

Oh the mysteries of life...
