Had a browse in Waterstones and it seems quite amusing. I especially like the outraged letter from a teenage boy complaining about Mark Curry getting his kit off. He concludes this is "revenge for the infamous corset programme" and says that "if a presenter is going to strip in future, could you please make sure it is Sarah?"
