A blind man was traveling in his private jet when he detected something was wrong. He made his way to the cockpit and got no response from his pilot.
The blind guy then found the radio and started calling the tower. "Help! Help!" The tower came back and asked, "Whats the problem?" The blind guy yelled, "Help me! Im blind... the pilot is dead, and were flying upside down!"
The tower comes back and asked, "How do you know youre upside down?" "Because the shit is running down my back!"
