A man explained inflation to his wife thus:
'When we married, you measured 36-24-36. Now you're 42-42-42. There's more of you, but you are not worth as much.'
-- Lord Barnett
The 50-50-90 rule: Anytime you have a 50-50 chance of getting something right, there's a 90% probability you'll get it wrong.
-- Andy Rooney

First the powder, then the wadding, then tamp tamp tamp....
