It was a sunny day, the sun was shining, and it was nice out, so Percival McAleese took his young son to the park to play on the swings. He should have paid attention to the Greek chorus singing inhe bandstand, but he was engrossed in explaining to his young son about the time he'd torn someone's ears off in a fight in a pub. Don't worry, it was self-defence: someone had thrown a pint glass at Percival's face for almost no reason, and he instinctively spun his pool cue up to defend his face. The pool cue hit the pint glass, Percival's face was saved, but the two largest shards from the smashed pint glass returned to their thrower and sliced both her ears off. Percival's young son loved hearing that story.
When Percival McAleese and his young son were all the way over by the swings, the Greek chorus sang louder in the hope that Percival might hear. As it happens, he did hear. As it happens, he did speak Greek. As it happens, he didn't hear enough of the Greek chorus to be able to heed their warning: by this time they were shouting rather than singing, to get Percival to hear them, and an old man from a nearby house came out to complain about the noise. They had to promise to keep it down, and sing something nicer just for him, by way of an apology. By the time they could shout again, it was too late. The Greek chorus should have listened to the other Greek chorus who were singing to them, but they didn't hear them as they were concentrating on their own singing.
Percival McAleese pushed his young son on the swings. Higher and higher flew the swing, harder and harder pushed the Percival. The swing smacked Percival on the forehead and knocked him backwards. His legs flew up from under him, and his momentum carried him around in a backflip. In an amazing feat of gymnastic prowess, Percival's spinning legs found themselves on the swing, after having accidentally kicked off his young son. Percival was half stunned and half stunned, and so just stood on the swing. The swing gained momentum from Percival's spinning on to it, and did a full 360° loop of the swing's crossbar. Percival's young son hadn't seen all that had happened, so was only half stunned from being kicked off the swing. He stood up to work out what had happened, and the swing smacked him in the back of the head, and knocked him flying forward on to his face.
The swing continued to spin around and around, its chains shortening with each revolution. Percival shook off his being stunned and stunned, and wondered what he could do to escape his predicament of being on a runaway swing. He wondered slower than the chains shortened. When they reached their winding limit, he was flung from the swing with a jolt. Percival did the expected somersault in mid-air, and was all placed for the perfect landing, feet together, no movement. Feet together, no movement, would have placed his feet on the back of his prostrate young son's head. Percival bailed out from gymnastic purity in order to save his young son's life, and pulled his legs apart at the last second. He should have done so at the second to last second: Percival's feet caught his young son's slightly protruding ears and ripped them clean off.
An ambulance was called. The police were called. The ears couldn't be reattached, but Percival's young son was as well as could be expected. There were no eye-witnesses to what had happened: rather than playing in the park, everyone else in the whole world had been listening to one or other of the Greek choruses. Both Greek choruses, and those in their audiences who spoke Greek, confirmed Percival's version of events, but as they'd not actually seen it happen, the police had to arrest Percival for ripping his son's ears off. Percival's wife wanted to believe him, really she did, but she just couldn't.
