You know what's really gross? What I could go without seeing again? The inside of someones knee. That's real disturbing, especially when it's attached to a leg that is flailing about but also sadly lacking in skin or kneecap or ligament and is also flinging blood everyone. I thought the only time the femoral condyles should be visible were during a sterile and well planned knee replacement surgery, but I guess 23:00 in the ER trauma room is a great time too.
PSA: Don't get piss drunk and do a lot of drugs, then drive >100 mph on the freeway and get ejected from your car where you'll skid facedown across all four lanes. You'll leave your knee on the road, as well as most of your face and toes.
