Having a "play"
Reminds me of an idiot customer we had when I was doing TV repair for Rediffusion in the early 1970s. He regularly called in to say his TV had stopped workng - we'd sigh knowingly and go round to his house and put all the valves back into the correct sockets again. The valves, being rather hardier than chips, just tended to work fine again. We never had any idea why he liked to rearrange them in the first place!
