The Room/Headscratchers


 * Johnny is referred to as The Gonk, regardless of our opinion of our opinion of his actor wouldn't his character be closer to informed attractiveness?
 * Twice in the movie, Lisa says "You owe me one." Once she says it to Mark, and once to Johnny. No one ever explains what Lisa did for either one of them that they owe her one. Was that supposed to be some kind of catchphrase for her, or what?
