I was working for Granada TV Rental at the time. I think it was the late 70s and I was crouching down removing the back from a colour tv when a rather large Alsatian intent on giving me an olfactory appraisal began sniffing rather too close to my lunchbox for comfort. Because of this I abruptly stood up knocking a birdcage on a stand with my head. As it arced downwards it dislodged a clock on the mantelpiece. I’m not sure what happened first – the clock in pieces in the hearth or the budgie on the floor having a heart attack.
I think I managed to fix the TV in the end. The customer claimed for a new clock and the budgie recovered and lived to a ripe old age.
