A horse is a horse
Of course of course
And no one can talk to a horse,
Of course

That is, of course
Unless the horse
Is the famous Mister Ed!

Go right to the source
And ask the horse
He'll give you the answer that you'll endorse
He's always on a steady course
Talk to Mister Ed!

People yakkity-yak a streak
And waste your time of day
But Mister Ed will never speak
Unless he has something to say!

Oh, a horse is a horse
Of course, of course
And this one'll talk 'til his voice is hoarse
You never heard of a talking horse?

Well, listen to this:
". . . I am Mister Ed!"
