Let me start by saying I'm no MENSA candidate. I'm relatively smart, but certainly not a genius. Common sense is certainly more my gift than book smarts. And I certainly don't think having a college degree of any kind makes someone "smart."

However, you can't argue the common sense level of someone who can't figure out the concept of miles per hour. She seems so clueless about the concept that I can't help but wonder if she's just a really good actress. But the way her boyfriend sets up the question and reacts to the camera makes me think this is legitimate.

The scary part is, this woman will eventually be having children. *shudders*
