Near the end of the movie, after the 2 guys get in the car accident, look at the guy in the wheel chair. Look at his legs and then look at the section right under the seat of the wheel chair. You can see his 2 black shoes under there, which makes it so obvious that he's just kneeling down. (Of course they aren't really going to hack his legs off, but did they have to make it so obvious that he was kneeling in the seat?)
