These two virgins get married. As their first night together approaches, they wonder what they are supposed to do, them being virgins and all. So they decide to call the bride's mother. The mother tells them to get undressed. They do. Then she tells the bride that the groom should put the
"hardest part of his body into where you go to the bathroom." An hour later, when the bride's mother calls back and asks how everything went, the bride says,
"Well, I don't know, he has his head stuck in the toilet bowl, now what?"
