A mule is an animal with long funny ears
Kicks up at anything he hears
His back is brawny but his brain is weak
He's just plain stupid with a stubborn streak
And by the way, if you hate to go to school
You may grow up to be a mule
I love that song, I need to look up the lyrics to sing to my kids. I had it on some album when I was a kid, and remeber sitting in front of our huge console stereo listening to that.
