Once a smoker was smoking at the airport.........
A gentleman came & asked him.
How much do you smoke a day?
Smoker:- Why are you asking such a question?
Gentleman replied:-If you had collected that money instead of smoking,the plane which is in front of you, would have been yours.
Smoker asked that gentleman:- Do you smoke?
Smoker asked:- Does that plane belongs to you?
Gentleman replied:- No.
Smoker:-Thanks for your kind advice, but that plane is mine
Moral of the Story:-Unnecessary advice is injurious to health.
