The best explanation for why we haven't been back.
A couple of years ago, during our local pub quiz. Q. What was Valentina Tereshkova famous for. A. 1st woman in space.
Our former landlord, quiz master and local Sid the Sexist, was approached by a young girl from a team of students, complaining that they should have been awarded a mark for the right answer. "No" he replied "There hasn't been a woman on the moon. It dosen't need cleaning yet."
