Once there was a Seder headed by a female Rebbe. On the Seder plate was a crust of bread. A disciple asked, "Why...?" She told the story of Puah, a girl from a family of women, asking her Rebbe "Is there room in Judaism for a lesbian?" He said, "There is as much room for lesbianism as there is a crust of bread on the Seder plate." That is why this Rebbe had a crust on the Seder plate. -- based on the Oberlin College Haggadah.
