"What are the differences between computer and humanity??If computer get hot, there is a fan for the computer. If a man get hot, which will mean to much information in head, the humanity start to masturbate!But the question is why computer have one fan and humanity have two hands??It's simple as that!Fan can be replaced, but one hand can't be replaced if it's broken, so it's gave one more if you have problem with the one to use the other. Take it as a gift!"
