Stupid office trick: carpet skating

Love to hear what you HR pros and workplace attorneys have to say about this kooky product. The Hula Chair is one thing; it's silly and totally impractical. But Carpet Skates from Funslides could break your behind. Not that I wouldn't mind seeing one of these goons laid up for a while. (Would you believe a PR person for the product sent me this link? She writes, "There are some obvious safety issues surrounding the use of Carpet Skates, but I wanted to give you a heads up about fun, unique way that employees are breaking up the workplace monotony." Seriously.)
