Reminds me of a story one of my friends once told me.
He said Pakistanis were tough, real tough people. Real tough. How does he know? He (American-born) once made visit an uncle in Pakistan, for the first time. He wanted to go about his business, but noticed no toilet paper. And he said, 'Eh... uncle? How about what it is you do for, you know, cleaning the basement?' The uncle winked at him, and led him to a cupboard of sorts. And there, in the cupboard, there was a large collection of ROCKS !! Not the smooth kind either, but the kind that has lots of nooks and crannies, and painful grit to it, sandpaper-like. And that is why, my friends, Pakistanis are tough according to my friend.
