there's another vid floating around somewhere from QVC where their super sturdy multi-position step ladder collapsed under the guy. That one's funny too.
I was talking for a guy who used to direct for those shows - seems the salesmen are all really bored so they make crap up all the time just to see how bizarre they can get in the product descriptions. Doesn't really matter because the kind of person who buys stuff off of QVC won't generally know quality from lousy anyway
I'd guess he probably was hamming it up because he'd just claimed the sword was "razor sharp." On the other hand, the point got him, so it probably didn't feel too good.
