The Inchworm   Frank Loesser, from Hans Christian Andersen (1951)

Two and two are four, four and four are eight;
That's all you have on your businesslike mind.
Two and two are four; four and four are eight.
How can you be so blind?

Inchworm, inchworm, measuring the marigolds,
You and your arithmetic, you'll probably go far.
Inchworm, inchworm, measuring the marigolds,
Seems to me you'd stop and see how beautiful you are.
