Where's My Sibling?

For weeks, a six-year old lad kept telling his teacher about the baby
brother or sister that was expected at his house. One day his mother
allowed him 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 cried, "I think Mommy ate it!"
