Episode cast overview:


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

Did You Know?


After Sheldon introduces his first cat to Raj and Howard in the cafeteria, he exits the scene by saying that he needs to get the cat a saucer of milk. Many cats are actually lactose intolerant and should be given water instead. See more »


Sheldon winds up with 25 cats. However, in Season One's "The Fuzzyboots Corollary", he is thoroughly upset when Leonard indicates he is getting a cat, thus indicating Sheldon doesn't like cats. Leonard also mentions that Sheldon has asthma. And in Season Three's "The Plimpton Stimulation", Sheldon states that pets are banned according to the roommate agreement. See more »


Amy Farrah Fowler: Absolutely not. My colleagues and I are mapping the neurological substrates that subserve global information processing, which is required for all cognitive reasoning, including scientific inquiry, making my research ipso facto prior in the ordo cognoscendi. That means it's better than his research, and by extension, of course, yours.

Crazy Credits

CHUCK LORRE PRODUCTIONS, #297. Everywhere I look I see Ned Beatty. Not literally Ned Beatty. What I keep seeing appears to be his doppelgänger, or his evil twin, or a Ned Beatty wannabe, or simply some paunchy, red-faced, middle-aged sonuvabitch who has either the great misfortune or great good luck to look just like Ned Beatty. I would also venture to say that if you were to casually glance over your shoulder, you too would see -- not now, wait until it's cool... okay, now. See it? There are a suspicious number of Ned Beattys wandering around this country. If one were conspiratorially- inclined, one might even think that someone is growing a secret army of the rotund little bastards. Why? To what end? Retribution on an apocalyptic scale for the lifelong mocking the real Ned Beatty endured after appearing in the sodomy scene in Deliverance? Whatever the purpose, there's ample reason to be afraid. The only reassurance we can have is the knowledge that it's not nearly as scary as a whole bunch of Warren Beattys running around. See more »

"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".
