|This sitcom stars a free-spirited beauty and her socially challenged scientist friends but does not demonstrate any family values. Instead, some of the main characters are rooming together with people just met without being married, and all four leading men have dysfunctional relationships with one or both parents. In addition, the key character Sheldon Cooper is one of the most outspoken [[Atheism|atheists]] in sitcom history, which leads to both religious and cultural friction with his devoutly Christian mother Mary as well as his Jewish colleague Howard Wolowitz and Hindu friend Dr. Raj Koothrapali. The show is widely considered to have stolen its characters' personalities and their relationships to one another from an earlier sitcom, ''Friends''.<ref>http://www.sheknows.com/entertainment/articles/1110963/the-big-bang-theory-and-friends-similarities</ref><ref>http://whatculture.com/tv/15-similarities-friends-big-bang-theory</ref><ref>http://www.looper.com/10501/big-bang-theory-lot-like-friends/</ref>
