Episode cast overview:
Penny (as Kaley Cuoco)


Despite not considering her his girlfriend and visa versa, Sheldon and Amy are spending a lot of time together. This situation irks the gang, but especially Leonard as Sheldon's roommate, since they all detest Amy, who they consider sanctimonious and condescending. The gang's problem may self destruct when sanctimonious and condescending Amy has a fundamental disagreement with sanctimonious and condescending Sheldon, leading to the two deciding to break-up despite not having been boyfriend/girlfriend. Sheldon states that he is perfectly fine with the relationship ending, but his actions seem to imply otherwise as he replaces Amy with something else in his life. Concerned for his friend's state of mind, Leonard calls in the one person who he believes can get through to Sheldon. Written by Huggo

Sheldon and Amy are playing a made up game where they state that "In a world ruled by a giant beaver, mankind builds many dams to please it, the low lying city of Copenhagen is flooded..." The city of Copenhagen is located on an island off mainland Denmark and on the coast so damming rivers would never cause it to flood. See more »


Mary Cooper: Sheldon, sit down. Let's talk.
Sheldon Cooper: All right. But you're not fooling me. Whenever you say we have to talk it means you want me to listen.
Mary Cooper: Then stop talking.
Sheldon Cooper: Yes ma'am.

"The Zazzy Substitution" is another very worthy ep of "The Big Bang Theory"
1 October 2011 | by (Baton Rouge, La.) – See all my reviews

Now that Sheldon has Amy for a girlfriend ("Don't call her that!"), Amy's judgemental attitude is annoying all his friends especially Penny after she makes the mistake of calling them Shamy. But the relationship seems over soon when Amy takes a lower opinion of Sheldon's theories than he tolerates of. Still denying his feelings for her were of the romantic kind, he buys a cat for companionship. After that cat becomes a family, Leonard calls his mother for help...Another funny ep of last season's "The Big Bang Theory" with Mayam Bialik fitting in nicely with the gang and what a pleasure to once again see Laurie Metcalf as Sheldon's mom. So on that note, "The Zazzy Substitution" is another worthy episode of "The Big Bang Theory".
