Pigs and the Market

I was watching the show "Dirty Jobs" the other night and this particular episode was about pig farming. The host of the show said that when he would say the rhyme ..."this little piggy went to the market..." he always thought of the little pig going shopping but in fact, the pig was going to be sold at the market. I always thought of the little pig going shopping, too!!! And now the rhyme has taken on a whole new meaning and lost it's charm. Whatever will I tell my grandchildren!!??? (when I have them)
