An Engineer or A Doctor? An Engineer was unemployed for long time. He could not find a job so he opened a medical clinic and puts a sign up outside: ""Get your treatment for $500, if not treated get back $1,000."" One Doctor thinks this is a good opportunity to earn $1,000 and goes to his clinic. Doctor: ""I have lost taste in my mouth."" Engineer: ""Nurse, please bring medicine from box 22 and put 3 drops in the patient's mouth."" Doctor: ""This is Gasoline!"" Engineer: ""Congratulations! You've got your taste back. That will be $500."" The Doctor gets annoyed and goes back after a couple of days later to recover his money. Doctor: ""I have lost my memory, I cannot remember anything."" Engineer: ""Nurse, please bring medicine from box 22 and put 3 drops in the patient's mouth."" Doctor: ""But that is Gasoline!"" Engineer: ""Congratulations! You've got your memory back. That will be $500."" The Doctor leaves angrily and comes back after several more days. Doctor: ""My eyesight has become weak."" Engineer: ""Well, I don't have any medicine for this. Take this $1,000."" Doctor: ""But this is $500..."" Engineer: ""Congratulations! You got your vision back! That will be $500.""
