A man robs a bank and takes hostages.
He asks the 1st hostage, "did you see me rob the bank".
The hostage answers "yes". The robber, promptly, shoots him in the head. Then he asks the 2nd hostage if he saw him rob the bank. The hostage answers, "no, but my wife did" . . . ;->
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.!
