Comic Relief week hots up tonight with two different approaches to making celebrities suffer for our money. First, at 8:00pm, we have a team of famous faces, including Gary Barlow and Ronan Keating, trying to scale Mount Kilimanjaro in Tanzania, a very unfunny physical challenge that should properly test their mettle. No offence, but you have to wonder if the less fit ones (we're looking at you, Chris Moyles) can make it all the way to the top. But would you rather sweat under the African sun or under the withering glare of Sir Alan Sugar? The now-traditional celebrity version of The Apprentice can be relied on to produce memorable spats (for example, Trinny Woodall attacking Piers Morgan with a biro). And this year the task is to design and market a special Comic Relief product, with a female team that includes Ruby Wax, Carol Vorderman and Patsy Palmer taking on a men's team where the egos clashing include Jack Dee, Jonathan Ross and Gok Wan. It should be a hoot.
