When the internet goes bung, call the washing machine man

Sometimes when I turn the tap on and someone else is on the phone in the other room, I think, 'oh, hang on. Will this interrupt the supply to the telephone?', for some reason acting on the supposition that telephones run on water.

Then again, the other day, when the washing machine stuffed up, I called the repair man. And then, when I was speaking to him, the phone stuffed up too. Perhaps I'm on to something after all...
