You have mistaken Baron Orczy for Doctor Seuss.

Dr. Seuss would have said something more like:

You may wear your underwear
Under here and under there
You may wear it anywhere
Yes, you may wear your underwear.

You may wear it in a house.
You may wear it with a mouse.
You may wear it in a box.
Wear it just like DnvrFox.

You may wear it on your head.
You may wear it in your bed.
You may wear it in a plane.
You may wear it on a train;
But it won't be to your liking
If you wear it while you're biking.

Let me make this very plain,
Underwear will cause you pain.
It will chafe and it will bind
It will make you lose your mind
You'll get sores on your behind
Hairy palms and you'll go blind.
This, I'm sure, is what you'll find
If you wear your underwear
Under bike shorts anywhere.
