Plane Crash

[Rondy]

Three men survived a plane crash over the Sahara Desert: a blind man, a deaf man and a man in a wheel chair. After staggering through the desert for a couple of miles they came upon a river. The river was very wide but they could see signs of human life on the other bank. "Ah well," said the blind man, "Here goes," and dives in. He reaches the other side, rubs the water from his eyes and shouts out: "I can see, I can see!"

The deaf man also dives in, reaches the other side and shouts out: "I can hear, I can hear!"

The bloke in the wheel chair, by now in a high state of excitement, lets his chair slide into the water and pedals furiously to the other side. He eventually reaches the other side and shouts out:" Look, I've got new tyres, new tyres."
