Why did the Asian parents have an Asian baby?
Two wongs don't make a white.
Listen here, nimrod. The joke is a play on words. It uses the phrase "two wrongs don't make a right" and replaces "wrongs" with "wongs" (a reference to a stereotypical Asian last name) and "right" with "white" to imply that Asian parents will have Asian babies. You are such a dumbass!
