''Why are fire engines painted red?

  Firemen's suspenders are red, too.

  Two and two are four.

  Four times three is twelve.

  Twelve inches in a foot.

  A foot is a ruler.

  Queen Mary is a ruler.

  Queen Mary sailed the sea.

  The sea has sharks.

  Sharks have fins.

  The Russians conquered the Finns.

  The Russians' color is red.

  Fire engines are always rushin'.

  So that's why they're painted red!''

  I didn't write this. But this is how stuff is stored in your
  mind.
