The Dead Hooker Juxtaposition is the 19th episode of the 2nd season of The Big Bang Theory.
A new tenant moves in to the apartment above Leonard and Sheldon, a sexy young actress named Alicia. While Leonard, Howard and Raj go ga-ga over her, Penny thinks she's just using them and is not jealous of her at all, while Sheldon worries that she'll be too noisy.
- Attention Whore: Both Penny and Alicia over Leonard, Howard and Raj's tech-savvy knowledge and physical assistance in helping her move into the apartment.
- Bad News, Irrelevant News: For Penny. The bad news is that Leonard, Howard and Raj keep ignoring her to go do tasks for Alicia and so Penny can't get Leonard to do all the favors she asks of him such as setting up her printer. The irrelevant news is that she got Sheldon the wrong mustard.
- Be a Whore to Get Your Man: Penny dresses up in a very revealing, promiscuous dress to win Leonard back from Alicia. Though of course Alicia was also wearing something similar, so it doesn't work. Penny then buys Chinese food for the guys to win them back, only for Alicia to offer them Chinese food as well in exchange for helping her move her things into her apartment room right above theirs.
- Cat Fight: Penny and Alicia finally get in a brawl on the hallway. The guys come upon them and Howard preemptively stops Leonard from breaking it up. The majority of the fight is off-screen with only Penny seen afterwards. Penny got a black eye and a punch in the mouth, Alicia possibly looks just as bad but is apparently in good enough shape to have sex.
- Comically Missing the Point: Related to Straw Hypocrite listed below, Penny complains that Sheldon is making an unrelated analogy, even though she's the one clearly doing so, not Sheldon.
- Distracted by the Sexy: Leonard, Howard and Raj.
- Dude, Where's My Reward?: Sheldon complains that his reward for helping Howard move all of his belongings in boxes from Howard's house to the apartment room above theirs should be more than just a pizza. To calm him down, Raj lies to Sheldon that instead the reward will be a choice between a mountain bike or a PlayStation 3. Sheldon eagerly goes for the PS3.
- Female Misogynist: Penny's comments and attitude towards Alicia imply she is misogynistic towards other women.
- Foreshadowing: Sheldon worried Alicia would be noisy. Turns out he was right.
- Gold Digger: Implied with Alicia. She suddenly asks Penny when they were doing laundry how much she thinks physicists make.
- Green-Eyed Monster: Although she won't admit it, Penny is clearly jealous of Alicia for taking the guys' attention and also for having a successful acting career (Penny's never started).
- Hypocrite: Penny has no right to call out Alicia for how she treats Leonard when she takes advantage of Leonard all the time too. When Alicia points this out, Penny stays silent for a bit (being unable to think of a suitable comeback obviously) then says Alicia is way out of line.
- Insane Troll Logic: Howard's mother completely opposes the idea of Howard moving out to live on his own in the vacant apartment room right above Leonard and Sheldon's room yet she tells him to "fly out of the nest" already.
- It's All About Me: Penny and Sheldon as usual, as they spend the whole episode and spend most of their screen-time complaining about Alicia. Penny resorts to even getting into a physical fight with her at the end.
- Momma's Boy: Howard prioritizes appeasing his loud, obnoxious and selfish mother over his as well as Leonard and Sheldon's best interests by agreeing to stay with her just to keep her company rather than take up the vacant room so that a noisy neighbor can't do so.
- Not Distracted by the Sexy: Sheldon.
- Shout-Out: Leonard mocking Sheldon with "They're heee-ere" as the new tenant above their room has moved boxed packages in is a take on Carol Anne from Poltergeist.
- Straw Hypocrite: Penny straight-up. She complains that Alicia is taking advantage of Leonard with her good looks. Sheldon points out she does the same thing as well and that it all started back in the pilot episode where she asked Leonard and Sheldon to retrieve her television. Penny complains that's "not" related, commenting "Apples and oranges, Sheldon!" Later on in the episode Alicia calls out Penny on her hypocrisy.
- They Wasted a Perfectly Good Sandwich: Leonard, Howard and Raj all abandon their Chinese food Penny bought for them just to help out Alicia who offers them Chinese food as reward.
- Weaksauce Weakness: Discussed.
- What Happened to the Mouse?: Alicia is never seen or mentioned again after this episode. The guys presumably decided to stop doing favors for her and stop talking to her after her fight with Penny or because she hooked up with an executive from CSI.
