once upon a time...
there was a duck
and it liked to waddle around like ducks tend to do.
And then one day it met a ninja who liked to be a ninja.
They and became very good friends.
And then one day the ninja died and the duck was sad, but then
the duck met the ninja's sister.
They became good friends and talked about her brother the
ninja and things that ducks like to talk about.
Then, years after the duck and sister died the descendants
of the two are still friends to this day.
And that is why ducks like ninjas.

The End.
