As soon as Fred gets out of bed - Jack Prelutsky

As soon as Fred gets out of bed,
his underwear goes on his head.
His mother laughs, "Don't put it there,
a head's no place for underwear!"
But near his ears, above his brains,
is where Fred's underwear remains.

At night when Fred goes back to bed,
he deftly plucks it off his head.
His mother switches off the light
and softly croons, "Good night! Good night!"
And then, for reasons no one knows,
Fred's underwear goes on his toes.
