'''Airdate: November 25, 2012'''

Depressed over growing older (and upset when Peter recites an insensitive poem about her aging), Lois has a midlife crisis, where she becomes the wild party girl she once was and sets out to have sex with pretty boy pop singer, Music/JustinBieber. Meanwhile, Stewie gets a pet turtle who's out to kill him.

!! "Lois Comes Out Of Her Shell" provides examples of '''(YMMV goes [[YMMV/FamilyGuyS11E6LoisComesOutOfHerShell here!]])'''

* AccidentalHero: By replacing Meg's sleeping pills with allka-seltzer, Sheldon just may have saved her life.
* AxCrazy: Sheldon is one psychotic turtle.
* BeforeMyTime: Bieber doesn't get the references to ''Film/TheGraduate'' and ''Film/AmericanPie''.
* BigDamnHeroes: Sheldon is about to finally kill Stewie, but then he's jumped on by [[Franchise/SuperMarioBros Mario]].
-->'''Stewie:''' Oh, my God, Super Mario? What are you doing here?\\
'''Mario:''' I jump on a turtles, Stewie. It's not an exciting life, but it's my life.
* BlondeBrunetteRedhead: Lois and two other girls she hangs out with.
* DrivenToSuicide: Meg tries to kill herself by overdosing on sleeping pills, but Stewie's homicidal pet turtle replaces them with Alka-Seltzer tablets, so instead of dying she lets out a long burp.
* GainaxEnding:
-->'''Peter Griffin:''' Ladies and Gentleman, Mr. Conway Beiber.
* HollywoodMidLifeCrisis: the plot focuses on Lois going through a mid-life crisis. She starts speaking in l33t and text message abbreviations, wears skimpy clothes, gets a lot raunchier with Peter, and culminates with her trying to have sex with Justin Bieber. As expected, Lois is back to her old self by the end of the episode.
* JerkWithAHeartOfGold: Peter starts out as a {{jerkass}}, but eventually turns into this in the end. Brian was this because he suggested a party and called Peter out on his jerkassery. Lois too.
* MrsRobinson: Invoked. Lois is trying to seduce Music/JustinBieber and she refers to herself as Mrs. Robinson. Justin misses the reference.
* MsFanservice: Lois, more than usual. Her new look is really sexy with a skimpy outfit and different hairstyle. She has also a scene where she seduces Peter with GodivaHair and wearing only her panties.
* ReptilesAreAbhorrent: Sheldon.
