<P> Sheldon possesses an eidetic memory and an IQ of 187 , although he claims his IQ can not be accurately measured by normal tests . He originally claimed to have a master 's degree and two doctoral degrees , but this list has increased . Sheldon has an extensive general knowledge in many subjects including physics , chemistry , biology , astronomy , cosmology , algebra , calculus , economics , computers , vexillology , engineering , history , geography , linguistics , football , trains , Star Trek and in addition to being fluent in Klingon , has some knowledge of Finnish , Hindi and Mandarin . He also shows great talent in music , knowing how to play the piano ( as does Parsons in real life ) , the bongos , the recorder , theremin ( which Parsons learned to play in real life ) , showing some skill in Tuvan throat singing and also having perfect pitch . Although his friends have similar intellects to him , his eccentricities , stubbornness , and lack of empathy often frustrate them . Sheldon occasionally uses slang ( in a very unnatural fashion ) , and follows jokes with his catchphrase `` Bazinga ! '' which is now an officially registered trademark of Warner Bros. He is uncomfortable with human physical contact and has germophobia , which makes his exceptionally rare hugs extremely awkward and painful - looking . He also has hemophobia . Sheldon has difficulty coping when asked to keep a secret , when he is interrupted , or when he hears arguing . He is also a notary public and uses his knowledge in law and contracts usually for his own advantage and is always distressed when challenged in a legal aspect that he can not logically defend . In his mannerisms , Sheldon also shows symptoms associated with obsessive - compulsive personality disorder . Whenever approaching a person 's home , he must knock three times , then say the person 's name , and must repeat this at least three times ( where `` The first one is traditional , but two and three are for people to get their pants on '' ) , as a result of him walking in on his father with another woman when he was thirteen . Upon entering a person 's home , he must select the proper seat before sitting down . When it is suggested by Penny that he `` just sit anywhere '' , his response is `` Oh , no , if only it were that simple ! '' This extends to his inability to accept change . His rigidity in maintaining homeostasis often causes him frustration . Because of his rigidity and stubbornness , only his mother and Bernadette -- both possessing strong maternal personalities -- have shown the ability to order him to do things . </P>
