There once was a man,
who lived in a box,
a beautiful box made of blue.
He traveled the world with his beautiful box,
and made paradoxes at it too.
This man was smart,
and this man was wise,
and tried not to let the living die.
This man's name was the doctor,
and he's got a-lot of stuff to do,
but killing was not one of them,
which is so very true.
