In the beginning sequence when Sheldon is seen on the couch with his computer open and sitting in his lap; as the series of scenes progresses we observe his laptop magically closed then re-opened. When we finally see him close his laptop there is an audible thump as the screen contacts the keyboard. This sound is not heard in the previous scene where the laptop magically closes and opens. A second error occurs with the pillow that Sheldon is leaning on. It appears in different positions throughout this series of scenes.
