I once successfully challenged the outcome of a pub quiz. The question was, 'What English scientist determine the weight of the Earth?' The other side answered, 'Cavendish' and scored a point. I correctly and annoyingly pointed out that the Earth is in free fall and has no weight, so what Cavendish had figured out was the mass of the Earth.
