Go to the scene where Ray and Greg are standing by the lockers and Ray's asking if his shirt makes him look gay. After Buffy walks up to Greg he curses and bangs the locker with the hand holding his report card. You can see the outline of all the sections except there's no "DUMB-ASS" written on it. When they show a close up there is obviously a "DUMB-ASS" stamp. I thought it was weird...
