A blind man was describing his favorite sport: parachuting.
“But how do you know when you are going to land?” he was asked.
“I have a very keen sense of smell and I can smell the trees and grass when I am 300 feet from the ground,” he answered.
“But how do you know when to lift your legs for the final arrival on the ground?” he was again asked.
He quickly answered: “Oh, the dog’s leash goes slack.”
Ok, that was awful.
