"Doctor, are you sure I''m suffering from pneumonia? I''ve heard once about a doctor treating someone with pneumonia and finally he died of typhus."
"Don''t worry, it won''t happen to you. If I treat someone with pneumonia he will die of pneumonia only." . . . ;->
Father:Tumne college mai sub se mushkil kam konsa sikha.
Beta:2 kam sikhe,
Aik danto se bear ki botel kholna,
Dosra teiz andhi mai 1 teeli se cigarat jlana! ;-)
