Gary Lineker discovered a phone hidden in the BBC studio after coverage of the FA Cup tie between Wolves and Liverpool was plunged into disarray by porn noise "sabotage".
There were just 15 minutes of build-up to Tuesday night's third-round replay at Molineux, but the majority of them were interrupted by the same porn sounds frequently employed by internet pranksters. Lineker was left to awkwardly try and direct pre-match punditry involving Paul Ince, Danny Murphy and Alan Shearer.
Yet the noises kept coming at regular intervals, leaving fans up and down the country who had tuned into their televisions utterly bewildered. Much to Lineker and the pundits' relief, the match soon got underway, giving them the chance to unearth the cause of the sounds.
