Crapple

Jack drew a fruit from his satchel.
And said, "Boy this tastes just like scrapple."
And when he looked down,
his face turned a frown,
For he saw half a worm in his apple.

Jack grew a plant in his garden
His neighbor said "I beg your pardon--
I'm getting some calls
About hairy balls--
Is this something that I could take part in?"
