'I think I've lost my watch.'
'No, it'll be around somewhere - have you checked your car?'
'Yup, looked everywhere, can't find it.'
'Bugger. I really liked that watch.'
A day later.
'I've found your watch!'
'In the washing machine...'
'Uh oh....before or after a load?'
'After the second load...'
'At least you now have a very clean watch.'
However I am delighted share with you that closer inspection revealed those buggers were surplus to requirements- my very clean watch still works!
