I invited my boss and her husband over for dinner and while we were eating she asked my son, Little Johnny, what he learned about in school that day. I said that we usually play a "four clues" game where we have to guess and she thought that would be fun. So Johnny gave his first clue: It's kind of round and covered with hair. That didn't narrow it down much so he went to his second clue: It can be full of liquid that you can access through a crack. Nobody had an idea yet, though knowing Johnny I was starting to get anxious. He gave his third clue: When mommy and daddy were unpacking and changing from a day at the beach I peeked into their room and saw that mommy had one and daddy didn't. Still no guesses from anyone but I was starting to panic. Johnny gave his final clue: It contains the letters , N, U, C and T. My wife saved my career when she quickly blurted out COCONUT!
