Englishman lands into Karachi as a tourist - to check out what his ex-colony looks like half a century after independence..
Knows a few bits and pieces of urdu ..
Decides to take a walk at night - somehow wanders far away - ends up somewhere in liyari area. Now there he sees a man standing with his face to wall and obviously doing suusuuu against the wall - the wet tricklet of water flows down slowly to the road side..
The man is absolutely flabbargasted 
cant believe his eyes - HOW could a man pee in the street ..
Sees a passer by - stops him - points to the man peeing and asks in his tooti phooti urdu ..
Bai saab - idhar main poleece nahi PaKkarTaa 
and the innocent lyari ka shehzada replies…
Nahi saab - yeh kaam khud hi karnaa paRrta hay
