I thought I would share a story from when my older daughter was in 2nd grade. They were given an assignment to choose a word from the dictionary that they didn't know what it meant and then the teacher would help them figure out the meaning. So when her turn came, she told the teacher (and the class) what her word was - it was SCROTUM. The teacher (a young guy in his late twenties) turned red and pretty quickly moved on to the next student.
