A blind man was traveling in his private jet when he realized that something was wrong. He made his way up to the c**kpit but could get no response from the pilot. He felt around until he located the radio "Help Me! Help Me! I'm blind, the pilot is dead, and we are flying upside down" he screamed into it. The Tower comes back and asks him "How do you know your upside down?" The blind man replies back "Because the shit is running down the back of my neck!"
