I read something rather clever recently.
On my way in to work one morning I spotted a painter and decorator's van sporting the strap line 'Reducing grime, disorder and smear.' Nice line in itself, but if, like me, you live in the Thames Valley, it takes on a whole new level of meaning. That's because the strap line for the Thames Valley police, emblazoned on all its squad cars, is 'Reducing crime, disorder and fear.'
I've always found this rather amusing--as if the police force is some kind of private sector hit squad that needs to advertise its services in order to attract potential new custom.
Always good to know that one's sense of humour isn't unique. Or indeed warped.
