specs

My boss's specs just snapped.

'It's alright' he said, 'They are only £2.99 form the chemist down the road, they are always breaking.'

'Maybe they are always breaking because they are £2.99 from the chemist down the road' I said.

'Maybe' he said, 'but when they break I keep the bits to use as spare parts for when the next pair break. I've got a whole box of them'

There is some moral here but I can't quite work out what it is.
