How many Ethiopians can you fit in a bathtub? Who knows they keep slipping down the drain.
I'm not sure I understand. What do you mean by that?
They are starving and keep slipping down the drain, because they are extremely small.
It is really insensitive to make jokes about people in Ethiopia who don't have enough to eat. Food insecurity is a major problem in large portions of the world, and it is something we should try to address. I recommend reading more about this so you can see why joking about it is so awful.
