The world is overpopulated and this is down to 3 sets of people.....
1, Chinese (They have limited their numbers by restricting the number of children a family can have)
2, Niggers, in africa they have HIV / AIDS (unfortunately that is not working well enough to limit the population - maybe scientists can increase the potency of it???)
3, Muslims, We need to introduce one of the above - limit numbers or find a way to kill them off.
