Shadow Birthday

When Bob had his birthday birthdays, he always shared it them with his shadow.
Happy Birthday, Bob!
All of Bob’s friends would come over for cake and ice cream, and so did their shadows for the shadows of cake and ice cream.
Bob blew out the candles, and so did his shadow on the wall.
It was a race between Bob and his shadow to see who could open presents faster. It was always a tie.
Sometimes there was a goofy clown. Other times, a magician showed up to work his magic.
One year, a strange man came to make interesting shadow puppets.
The shadows of Bobby and his friends were entertained by the hands of the puppet-master.
Why? Well, since when have you seen a rabbit or duck turn into a pair of writhing hands?
