Watermelon (a pun in progress)

I met him again at the fruit stand. He was a seedy looking fellow. Our hatred stemmed from the time he assaulted me. I was only trying to root out the truth. He told me to leaf him alone or he'd slice me up, but the threat sounded hollow. I told him to use his melon, he was too green to know what he was getting into. Guys of his stripe always have yellow bellies, so he left town and returned to Green River.
