To appreciate the true effect, you should understand that C shouts the entire conversation, while running up and down the kitchen with wild abandon, waving a LEGO sword thing...
C ( my 4-year old son, running around the kitchen with a cape made of a multi-coloured blanket, and some LEGO in the shape of what might be a sword... or a building... it's hard to say ) : I'm a superhero!
Me : Excellent. What's your superpower?
C : Rainbows! (long pause) And super strength - so I can smash stuff!
(C throws LEGO sword thing to the ground where it smashes, spreading LEGO over half the kitchen.)
C : See?!?
