Three disabled athletes – a blind man, an amputee and a guy in a wheelchair – were flying back with the US team from the 2008 Paralympics when their plane crashed in the Nevada Desert. The trio were the only survivors and faced an anxious wait hoping that someone would rescue them. After two days there was still no sign of help, so, feeling really thirsty, they decided to set off in search of water. The amputee led the way, with the blind man pushing the guy in the wheelchair, and soon they found an oasis. The amputee waded into the water first, drank freely, and when he came out the other side, lo and behold, he had a new leg. Excited, he immediately encouraged his friends to do the same. The blind man offered to push the guy in the wheelchair, but the latter wanted to be independent and insisted that the blind man went ahead first. So the blind man walked into the water, drank liberally, and when he emerged the other side, lo and behold, he could see. By now the guy in the wheelchair was eagerly anticipating his dip in the oasis. So he wheeled himself in, drank copious amounts of water, and when he wheeled himself out the other side, lo and behold, he had new tyres.
