The universe of Drs. Leonard Hofstadter and Sheldon Cooper is endlessly complicated and infinitely hilarious as The Big Bang Theory enters the tenth dimension! Last season, Leonard and Penny went from neighbours to newlyweds with a nuptial excursion to Vegas. This season, they find themselves in a repeating paradigm as they re-create their wedding – this time with family including Penny's mother [Katey Sagal] and brother [Jack McBrayer] and Leonard's parents [Christine Baranski and Judd Hirsch]. Meanwhile, Sheldon has drafted a new Roommate Agreement as he and Amy engage in an experimental cohabitation. Howard and Bernadette prepare for the arrival of Baby Wolowitz, and Raj offers up his expert parenting advice – whether they want it or not! All 24 episodes prove a new hypothesis of inspired comedy that's nothing short of genius!
