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! ;-)
Newton''s 5th law:
Dunya Gol hai,
Chooha Billi say darta ha, billi Kuttay se, kuta Aadmi say, aadmi Biwi say, or Biwi Choohay say. Hence Proved. Dunya Gol hai.!
