Baby brother/sister

For weeks a six-year old lad kept telling his first-grade teacher about the baby brother or sister that was expected at his house.

One day the mother allowed the boy to feel the movements of the unborn child. The six-year old was obviously impressed, but made no comment.

Furthermore, he stopped telling his teacher about the impending event. The teacher finally sat the boy on her lap and said, "Tommy, whatever has become of that baby brother or sister you were expecting at home?"

Tommy burst into tears and confessed, "I think Mommy ate it!"
