Whole Lotta Shakin Goin On...

"According to CNN: 'Seventeen people performing a vigorous Tae Bo workout caused tremors that forced the evacuation of a South Korean skyscraper earlier this month, the building's owners say. Scientists recreated the event in the 12th floor gym, according to a report in the Korea Times.' I don't know which is scarier, that they made such a flimsy skyscraper, or the sight of 17 scientists doing a Tae Bo workout. Hopefully they're better at it than the scientists I've seen in the gym."
