In the scene were Jake is in the bed already after telling Christy he was really tired and didn't want to be bothered he rolls over. She comes out of the bathroom & of course fanning the room from all of his cologne. Christy lays down in bed flat with no pillow behind her head. In the next scene showing Jake's face & Christy behind him in bed she now has a pillow under her and is much higher up in bed.
The scene where Jake and Christy are arguing and she yells the line "I'd go BAREFOOT." was used in a scene in the movie "Planes, Trains and Automobiles" about a year before. Moreover, Kevin Bacon, who starred in SHAB, has a cameo in the beginning of Plains/Trains.
