I was convinced until maybe five years ago that the end of the Christmas carol "Silent Night" was saying that the Baby Jesus was sleeping in heavenly peas, not peace. I couldn't figure out what God had put in those peas that made them so good and nice to sleep in. To this day my father sings, "sleep in heavenly peas and corn," because at my house we always have corn with our peas.
