Baby in a Cereal Box?

I was visiting friends. The woman was feeding her newborn baby on her bed and the baby slipped down the bed, which was tilting at an angle. The mom caught the baby by the collar and we were all laughing about it. She continued feeding the baby and we were talking about what had just happened, when the baby slipped again, but this time out of sight. The husband and I were searching all over for the baby but could t find him. The mom kept saying "oh my god, the baby's dead, I killed the baby". I was beginning to think she was right and was starting to panic but then at the foot of the bed there was a cereal box and I grabbed it and shook it and all of a sudden the baby's head popped out confused but laughing.
