Sheldon: This seat is ideally located both in relation to the heat source in the winter and a cross breeze in the summer. It also faces the television at a direct angle allowing me to immerse myself in entertainment or game play without being subjected to conversation.
Sheldon had positioned a lawn-chair at this particular point and "placed it in a state of eternal dibs".
Sheldon: Cathedra mea, regulae meae. That's Latin for "my chair,my rules".
While initially Sheldon did not want to be able to engage in conversations when sitting in his spot (0322), three years later Sheldon's explanation to Penny why he chose this particular spot had slightly changed. He now pointed out that "it faces the television at an angle that is neither direct so that it would discourages conversations nor at an angle that would causes a parallax distortion" (0101).
- Sheldon describes his spot as a "single point of consistency in an ever changing world". He says that if his life was expressed as a function in a four-dimensional Cartesian coordinate system, this spot, when he first sat on it, would be "0,0,0,0" (0216).
- With the exception of Penny in The Pilot, he does not tolerate when anyone else sits in his spot, even when he is not in the apartment (0216). Penny frequently ignores this and try to sit there, just to be told to move (0203,0204,0205, 0402). When Leonard's team wins the Physics Bowl he teases Sheldon by placing the trophy in his spot (0113).
- Sheldon knows his spot so well that he notices if the cushion is turned around or a different cushion is put in place (0216).
- He's happy to be back in his spot after a long time away, saying "hello old friend, daddy's home" (0301).
