Once I went to an eye doctor to get an eye check-up and was surprised when the doctor didn't test my eyes. Instead he just sat down and said "The economy will improve, and your job will be safe". Confused, I asked what he meant, and he responded "Pollution levels will drop with the increased usage of fuel-efficent cars". Again, I was puzzled and asked what he was talking about. He said "Your investments will all pay off in the near future". Frustrated, I got up and left the office. Only as I was walking out of the building did I see that the sign on the front door said Optimist, not an Optometrist.
THIS JOKE IS STUPID, BUT FREE.
