h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Hi there, I remember watching an old episode of that show when someone wanted to be on a specially written Doctor Who episode with Colin Baker who had an outfit just like his. Me, if I had a wish it would be first a bit difficult as that I live in the states, but I just would like him to give a wish to a kid who is terminally ill to give them a request, as long as it doesn't conflict with the management's viewpoints on certain subjects (whatever they may be).
