Time to return to the Big Bang for the week. Will Sheldon whine about nothing? Will Howard say something awkward? And last, but not least, will Raj ever get a decent storyline? Let's watch.

Amy and Sheldon have finished watching Indiana Jones, and he asks her how she feels. This is getting uncomfortably sexual. Is it just me, or does he have his hand on her leg??? Sheldon of all people! However, Amy's response is a tepid "good", especially since she took the phrase "losing your virginity" a tad more literally than Sheldon's interpretation of "seeing Raiders of the Lost Ark for the first time". Sheldon apologizes, saying he should have told her "You're about to have your world rocked on my couch." Amy concedes that she did like the movie, except for a minor "story problem". Sheldon condescendingly tells her he's a real fan, and if she wants to find a problem he hasn't seen, then all right, go ahead. She tells him that Indiana Jones had no real impact on the outcome. Sheldon protests, but Amy points out that the Nazis still would have found the ark without Indy. Sheldon is crushed.  Looks like a Shamy split is imminent. Opening credits.

Penny and Leonard meet up in the hallway, where she shows him her new college textbook - "The Disappointing Child" by Beverley Hofstadter. As you may have guessed, an alternate title could have been "The Complete History of Leonard". Leonard is devastated, Penny thinks it's not so bad. He asks that she find a new book, which I think is not unreasonable. Penny can't see his point. Okay, just because she doesn't have a doctorate doesn't mean she's thick as a post. His sex life also overlaps a lot with his childhood patterns. Things are getting uncomfortable, fast.

Raj is making a dating profile, along with Stuart (and is still gay-without-being-gay), Sheldon is reading Amy's favorite books to try to ruin them for her, in revenge for the Indiana Jones incident. The guys are confused, until he explains what she noticed about the plot. Their minds are just as blown. A big argument ensues. Looks like war has been declared.

Penny keeps bringing up stuff from the book, which Leonard expressly asked her not to do. He is understandably annoyed. She tries to analyze him. GOD, Penny's insufferable this episode. Can't she take a hint? Anyway, she says she can make him feel better, and they wind up in bed.

Raj is getting Stuart ready for his dating profile, complete with full makeup job. Unfortunately, Stuart ruins it by not being able to smile without looking psychotic. Raj tries, he really does, but he's not up to the task. When they move on to their dating profiles, it appears that Raj will turn into the Henry Higgins to Stuart's flower seller - though he is rather incompetent in this area himself. Stuart is oddly reminiscent of Sheldon in this scene, I have to say...

Sheldon can't find any flaws with Pride and Prejudice, and thus can't ruin Amy's favourite book, which drives him wild. Clearly he's never been to a lit lecture in his life. He is similarly unsuccessful with her favourite comic, Marmaduke. Leonard just wants to go out and join Penny for a football game, but Sheldon firsts asks him if he knows what else Amy likes. Even though Sheldon is the boyfriend here. Leonard leaves in disgust.

Leonard's reluctant to hang out with Penny's friends, and Penny correctly deduces that he's still mad about the book. They get dinner and watch the game at home instead. Well, thank GOD Penny finally did something remotely sensitive.

Howard walks in at work to find Penny and Leonard tenderly saying goodbye to each other. Leonard has been "playing sad" the whole time in order to guilt trip her into favors. It's working nicely for him - they just had sex at work. Sigh. Howard considers doing the same.

Sheldon makes a Skype call to Amy. He's inviting her for a spontaneous date night, this time with the show of her choice, which just about knocks her socks off. She's a bit suspicious, but agrees. They're on for a Little House on the Prairie date night. Sheldon looks completely diabolical at all times.

Meanwhile, Howard is trying the "sad Howard" tactics on Bernadette. He's way less successful. Instead of sex, he's stuck with dishes. Bernadette is not high on sympathy.

Raj and Stuart have completed their dating profiles and are eagerly awaiting a tidal wave of dates. It's maybe the most exciting moment of their lives.

Amy and Sheldon start up Little House as Amy fondly reminisces about its impact on her childhood. As it plays, he whispers unsavoury details to her about its filming practices and lack of accuracy. Amy instantly figures out what he's doing, and she's mad. He explains that her takedown of Raiders really hurt him. She apologizes. Christ on a cracker, why is Amy always the one to apologize when Sheldon is generally the asshole? Grrr. Sheldon proceeds to pick apart Garfield while Amy stares at him like he's from Mars. As usual.

Leonard walks in to find Penny waiting for him in a skimpy negligee. She means to make him feel better, like the nurse who likes to - in Ferris Bueller. Leonard takes the bait. She heard about his ploy from Bernadette, and has tricked him by bringing his mom in via Skype. And boy, is it good to have the incomparable Christine Baranski back. I love her in everything she does, and this performance is no exception. She completely destroys him in a matter of lines concerning his Freudian fixation. Leonard wails, but no one comes to help.

No one has messaged Raj and Stuart, who decide that online dating is for the birds. They go out to a bar and find that that is terrible, too. They just can't win...

The guys sit around watching Raiders of the Lost Ark, desperately trying to find a way to overcome Amy's theory. They finally decide that Indy saved the day through careful filing. Leonard ruins it, pointing out that he was incompetent at that, too. Back to the drawing board.

Well, this episode worked out. Lots of good laughs and some fun Amy-Sheldon and Leonard-Penny plots, even if we've seen them before. Just because it's been done doesn't always mean it's bad. And Christine Baranski is always welcome, even in a brief performance. Join us next week for more nerdtastic adventures!
