Lyrics & Book Excerpt
GOD 1, GOD 2, MAN, ANTIMAN:
Think of the value
Of your two opposable thumbs
They’ve always been our good chums
They can thumb wrestle
Help us count to ten and hitchhike
They fit in mittens
I’m sure they could plug a dike
With only fingers
What would hungry babies have to suck?
Little Jack Horner
Would’ve found himself plum out of luck
Sit there twiddling
But the thumbs no doubt deserve a hand
For their hand in
Helping bring about the rise of man!
