Rick is planning on scoring with Karen and wants to borrow Gary's grandmother's house key to do "the deed". (Gary's grandma died and no one is living in the house.) Rick and Gary pass each other on the stairs at school and Rick asks for the key. While they are talking, about 15 people pass by on the stairs. One of the first guys is coming DOWN the stairs wearing a blue/gray button down shirt. At the end of the scene, the same guy again comes DOWN the stairs, though he never was seen going UP. Apparently, it was a fake stairwell and the directors ran out of extras and just had people running around the set to keep people coming.
