We were barely aware that Big Brother was still on TV, let alone that they had reached their seventh season, but this televised social experiment is apparently still going strong. This is probably due to the fact that the formula of attractive people + exhibitionism + hot tubs = television gold. Four of the friendliest housemates from the current cast turn a relaxing Jacuzzi session into group shower party after the jump, and while it's not nearly as salacious as we would like (you'll have to catch the foreign versions for the really good stuff), it's pretty much the most exciting thing you'll see on network primetime this summer. Next to all those "Law and Order" reruns, of course.
