Boy, look at the letter A
Cover your left eye, cover your right eye

And will you please explain
What are you seeing again
When the letters grow small

Boy, look at the room
Cover your right eye, look at my hand

And will you say to me
How many fingers you see
With one eye open

Boy, your eyes are much bigger now
Bigger than your stomach, open them once again

And will you please say to me
How many fingers you see
With one eye open
