It happened: Mulla Nasruddin was getting fatter and fatter, stouter and stouter. The doctor advised a diet.
After two months Mulla went to see the doctor. The doctor said, 'My God! It is a miracle! You are even fatter than before -- I cannot believe my eyes! Are you strictly following the diet I gave you? Are you eating only that which I prescribed and nothing else?'
Nasruddin said, 'Nothing whatever! Of course I'm following your diet.'
The doctor couldn't believe it. He said, 'Tell me, Nasruddin, nothing whatever?'
Nasruddin said, 'Of course! Except my regular meals.' Regular meals PLUS the diet the doctor has prescribed.
