Long have I searched for an adequate way to spot the lesser members of society; the less intelligent, the IQ-impaired, the dumbasses, have you. I often used how many episodes of the Jersey Shore a person has seen as a quick gauge, but it became less and less practical. Luckily, this was right around the time Planking started becoming popular.
There was a slight scare when people started falling to their deaths, but then the Prime Minister of New Zealand's son planked a sofa. Now we're back in business.
