How much ground would a groundhog grind if a groundhog could grind ground ?

A groundhog would grind all the ground if a groundhog could grind ground.

(tune of I’m a Little Teapot)

I see a little groundhog, furry and brown,
He’s popping up to look around.
If he sees his shadow, down he’ll go.
Six more weeks of winter – oh, no!
