What's so good about an Ethiopian blow job? You know she'll swallow.
Is this joke supposed to be racist?
No, I'm just saying that because they are starving and poor, they'll do anything for food, even give a blow-job.
You wouldn't really make anyone laugh with such a crass and terrible joke, which is why if that's what you're going for then you should try some new material. No one will find it amusing that you're making fun of starving people and implying that they would all be easy sexually.
