Why can't two Asians have a white kid?
Because two wongs don't make a white.
Listen here, fetus. You're not very bright, are you? This 'joke' is playing on the sound of the words 'two wrongs' and 'two wongs' which uses the stereotype that Asian people pronounce 'r' as 'w'. It is not funny. It's actually incredibly ignorant. People don't get to choose what race they are.
