I consider myself blessed to have married an intelligent woman - a woman who is immeasurably smarter than the girl in this video. Although I haven't tested my theory, I am certain that my wife could accurately answer this man's question in 10 seconds or less.
ps, I hope watching this clip didn't lower your IQ. If it did, I apologize. Go watch some TED Talks and you'll feel better soon.
