Special charity edition of the business challenge show. Alan Sugar invites Jonathan Ross, Alan Carr, Jack Dee, Gok Wan and businessman Gerald Ratner to compete against Ruby Wax, Patsy Palmer, Carol Vorderman, Fiona Phillips and businesswoman Michelle Mone. Their brief is to create a special mystery product for Comic Relief, with just three days to invent, brand and market it. For the winning team, success - for the losers, the knowledge that one of them is going to get fired. That decision can be seen tomorrow night as part of Comic Relief 2009

I'm in, who else?
