A classic Charlie Claude Jones Story:
One day while at the East'ard Variety (Cab's), he noticed a man whom he sensed that he might have met before. He stepped up to the man and asked, "Sir, have I ever met you before?" The stranger responded, "I'm sorry, Sir, but I don't know that I have ever seen you before." Charlie then continued, "Well, have you ever been to Chicago?" "No," replied the stranger, "I have never, ever, been to Chicago." "Well, Charlie concluded, "I ain't either. It must have been two other people!"
