With more apologies to Dr. Seuss.

Young son, old son,

Wise son, bold son,

Mild son, mad son,

Live son, dad's son

This one was the second-born,

This one had a hunting horn,

But both were sadly battleworn.

Yes, one was young, and one was old,

One was wise, and one was bold,

One was sad, and one was mad

And also very, very bad.

Why was he bold and mad and bad?

I do not know. Go ask his dad.
