The Vartabedian Conundrum - S2-E10
Character mistake: Sheldon's is depicted as someone who rigidly adheres to his daily routines, such as knocking three times on doors and his bathroom schedule. In this episode, we see how he wakes up by performing his morning vocal tests. But throughout the show, whenever we see Sheldon wake up, he never performed this test again.
Suggested correction: Maybe he only does it when he feels he needs to. For example, when he thinks he is losing his voice or coughed a lot during the night. Just because we see it once doesn't mean that he always did/will.
