A silver TV is placed over a child's head. The cover is removed to the announcement, "And now the star of our show..." This proves that the box is empty with the exception of the child's head. The cover is replaced and the child gets out of the box. No sooner does the child get out of the box then the cover is removed and a rabbit is produced.
The box comes with a place for you to make up some funny commercials using construction paper. This can be done before you reveal the child's head. If you don't have a rabbit you can use a large load of spring flowers, silks, doves, etc.
