When I was about six, I always head people talking about the "F word." Since I didn't know the word in question, I assumed that they meant "fart." Now my teacher was very strict, and you got in big trouble for saying it. One day I was sent home with a letter, and upon seeing the envelope attached to my shirt, she asked "what did you do?" My reply? "I said the F word." My mother turned white and started to panic..until she opened the note, that is.
