Do you know who I am?
I am not Uncle Sam.
I am not a turtle,
And my name is not Yertle.
I am not an eagle,
Nor am I a fat beagle
Maybe I'm a creature,
But certainly not a teacher.
I know that I'm a friend,
A true one till the end.
I think I know who I am,
I am, I am...
I am me,
As unique as can be.
