The Onion
The Anglo-Saxons were fond of word-play, especially riddles. Here is a mildly rude one from the 10th-century Exeter Book, also in alliterative poetic form.
I am a wonderful creature, a pleasure to women, useful to neighbours; no citizens do I injure, except my destroyer. My build is tall. I stand in a bed, hair around underneath me. Sometimes there comes a very beautiful peasant’s daughter, lascivious girl, makes me all red, ravages my head, takes me in. She soon feels my closeness, she who forced me in, the curly-haired woman. Wet is her eye.
The answer? An Onion.
