If you want to captain your own submarine, or go for a skid in a No 14, if you want to meet a leading MP, or throw your teacher into the sea, Jim'll fix it. Have you got an unusual or special wish ? Jimmy will try to make it come true.

Some of your favourite fixtures from the past year.

"Dear Jimmy, may we... play the drums ? Mame a ship ? See how dolls are made ? Meet Percy Edwards ?" In this special programme Jimmy makes these dreams come true.

Emma meets the real James Herriot and becomes a vet for a day. Magnus Pyke describes a lunar eclipse with his hands tied behind his back. These are two of Jim's many 'fixes' for this special Boxing Day edition.
