The Loser Shel Silverstein

Mama said I'd lose my head
If it wasn't fastened on.
Today I guess it wasn't
Cause while playing with my cousin
It fell off and rolled away
And now it's gone.

And I can't look for it
Cause my eyes are in it,
And I can't call to it
Cause my mouth is on it
(couldn't hear me anyway
Cause my ears are on it),
Can't even think about it
Cause my brain is in it.
So I guess I'll sit down
On this rock
And rest for just a minute...
