A blind man went to the airport to fly in a small plane and the pilot asked him, if you're blind, why do you want to fly?" And the blind man said, he just wanted to have the experience. So off through the skies they went! The pilot had a heart attack and passed out and the blind man felt around and found the mike and keyed up and said, "Help, help, I'm a blind man flying upside down in a small plane and the pilot has passed out!" A voice came over the speaker that said, "if you are a blind man, how do you know you're upside down?" The man said, "because shit is running out of my collar!!!!"
