I see what you're saying. The thing is, George Lopez was born in California, and he is a U.S. citizen. That's why it's not like he's wrong, because the two girls are.
I wouldn't really consider it "cool" maybe "funny". And its funny because rather than getting upset and bitching about the girls obvious racial remark and complaining about why its racist and untrue and blah blah blah, he just went with an easy "fuck you"
Now take it easy, stupid.
