When Olivia is explaining to Russell how to play the video game, she mentions the buttons A, B, C, and D. Since it is a Nintendo Entertainment System they are playing, of those letters, only A and B were actually on the controller.
While Russell is babysitting Olivia and her friend they are playing Nintendo. The box is on top of the television which would make the controller cords cover the front of the TV, yet the cords look like they are coming from a shelf below the TV or on the floor.
