When my sister and I were about 8 and 10 years old we overheard some adults talking about Martin Luther nailing his thesis to the door. My sister decided to show off at Sunday school and told the teacher about Martin Luther nailing his feces to the Castle Church door. The teacher about wet her pants laughing as did a few of the older kids. We were bewildered until only a short time later when the real meaning of the word was explained.
