Bill, an experienced sky diver, was getting ready for a jump one day when he spotted another man outfitted to dive wearing dark glasses, carrying a white can and holding a seeing-eye dog by a leash. Shocked that the blind man was also going to jump, Bill struck up a conversation, expressing his admiration for the mans courage. Then, curious, he asked, How do you know when the ground is getting close?
Easy, replied the blind man. The leash goes slack.
