A silly song I made up for my kids called "Hungry woodpecker" that is related to a quotation in "The Dip" by Seth Godin:
"A woodpecker can tap twenty times on a thousand trees and get nowhere, but stay busy. Or he can tap twenty-thousand times on one tree and get dinner."
Hungry woodpecker Lyrics:
A hundred trees makes a hungry woodpecker
A hundred trees makes a hungry woodpecker
A hundred trees makes a hungry woodpecker
Peck peck peck
