< Fowl Whether >

[Emz]

        A randy young chap name of Powell, (very descriptive; however Powell is such a respectable surname for someone young and randy)
        Once mounted a frisky young fowl. ("frisky" implies that the fowl was consenting or willing, so at least Powell had that going for him)
        As he thrust in his pickle, (no size descriptor? :p )
        Her feathers did tickle; (okay so now we know the fowl is female)
        He laughed 'til he splitted his bowel. (is splitted even a word?) 

Forget everything I said, I love this and the pun title
