I've always liked disputing things. It sounds a little like proving something false but with out the proof and the obvious inconvenience of actually having to prove your point. I'm a prime example I dispute the Cavendish experiment, if he couldn't even get his arithmetic right how can I trust him to find G. Thankfully he wasn't trying to find G so all im disputing is his measurement of the density of the Earth. Thankfully a number of other folk have used torsion balances to measure G more recently.
