One day, a teacher was attempting to teach the names of animals to a class of 5-year-olds. She held up a picture of a deer, and asked one boy, "Billy, what is this animal?" Little Billy looked at the picture with a disheartened look on his face and responded, "I �m sorry Mrs. Smith, I don �t know." The teacher was not one to give up easily, so she then asked Billy, "well, Billy, what does your Mommy call your Daddy?" Little Billy �s face suddenly brightened up, but then a confused look came over his face, as he asked, "Mrs. Smith, is that really a pig?"
