You're nothin' but a "it"

Happy Independence day!

This mule tune is gonna be stuck in my head all day.  Thanks a lot Festus... No wonder he named his John mule "Ruth."

"You get no love cause you're nothin' but a it"
 
"I plumb forgive her because he's nothin' but a it"

And this, ode to the mule, in melodic patriotism.
