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

Amy Farrah Fowler: Why is she not taking our order?
Sheldon Cooper: I should have warned you. One has to navigate a labyrinth of social nonsense before one can be fed here.
Amy Farrah Fowler: Really? I assumed an establishment called the Cheesecake Factory would function more efficiently.
Sheldon Cooper: It's how they lure you in. I believe it's called bait and switch

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 »

User Reviews

not my concern nor my intention, but fans will be offended
3 April 2016 | by lidia-9See all my reviews

How can anyone watch this mind numbing, brain killing silliness?! I put in some time trying to understand... couldn't find a review explaining anything. All so called "reviews" I read here are in fact simple summaries of respective episodes. Honest question, is this show really popular, and if yes, can someone explain? I usually watch up to five minutes whilst multitasking. But I did make the effort of watching two WHOLE episodes, made me feel like doing something else. Anything else really, like cleaning the oven, washing greasy pans, cleaning the garage (which I did, thank you very much TBBT). I figure I watched the wrong episodes? Either that, or we failed in raising the next generation... I see two ways of "defending" the show: by attacking me (unknown person, unknown level of success), or by commenting on the qualities of TBBT. Help yourself to whatever suits you. If you're neither my spouse nor someone who works for me, "stick & stones may brake my bones [...]".
