A horse can't enforce, of course, of course,
And no one can talk to a horse of course
That is, of course, even if the horse is the famous Mr. Ed.

To credit the source, you name the horse
The copyright office just can't endorse
a right to chart the artwork's course.
Not for Mr. Ed.

People litigate up a streak and waste your time of day
But Mister Ed will never sue except via ASPCA.

A horse is a horse, of course, of course,
And this one'll paint with his head as force.
You never heard of an artist horse?

Well listen to this. Claim it's yours instead!
