I spent many hours as a child loving Shel Silverstein's book of poems, Where the Sidewalk Ends. This was definitely one of my favorites:
No Difference
by Shel Silverstein
Small as a peanut
Big as a giant,
We're all the same size
When we turn off the light.
Red, black or orange,
Yellow or white
We all look the same
When we turn off the light.
So maybe the way
To make everything right
Is for God to just reach out
And turn off the light!
