This is a classic that's been buried in the FWP archives. You see it all... from human furniture to pile-ups and much more. At one point you have Kat laying on Herman full weight while Lolla's sitting on Kat full weight. In another scene you have Lolla facesitting both Kat and Herman at the same time. You have full weight face bouncing and Lolla sitting on Kat's lap while Herman struggle below.
