Two Wongs Don't Make a White

Okay, Bob, listen up. You're not the sharpest tool in the shed, are you? This joke relies on a pun using the word "wrong" and a racial slur that sounds similar to "wrong". It implies that Chinese people cannot have white children due to their ethnicity, which, as you know, is utterly ridiculous, right? This is playing on stereotypes, using offensive terms, and is generally not cool. You should know better.
