Why would the holocaust never work on pakis? Good luck trying to convince them to take a shower.
Oh dear, that is quite offensive.  What is the basis for making such a statement?
Pakistanis are dirty and don't take showers.
You shouldn't make hasty generalizations about an entire country of people.  I doubt that many Pakistanis do not shower if they are able to.  Maybe we can watch a documentary on their culture together and gain a better perspective?
