This one's just in time for shabbat! Uncle Moishy and the Mitzvah Men, a Jewish American "edutainment" group, sing songs that convey the religious practices and philosophy of Orthodox Judaism. Here, "The Pizza Song" highlights the virtue of being nice, kind, and polite—you'll notice how Uncle Moishy did not have a conniption during any of his slice accidents. Oy vey.
