A blind man was flying in a small plane with his brother, the pilot, when his brother suddenly clutched his chest and died.
After finally finding the radio, the blind man called for help and was answered by an air traffic controller at a nearby airport. "You've got to help me! I'm totally blind, the pilot of this plane is dead, and we are flying upside down!"
The air traffic controller answered "I understand that the pilot is dead and you are blind, but if you are blind how do you know that you are flying upside down?"
"Because I have shit running up my neck!!!"
