- Critical Research Failure: Apartment Building Managers/Supers, while often provided housing for their work, still receive a paid salary (usually near minimum wage).
- Nearly all of the struggles Christy goes through to become a lawyer don't make much sense for a show explicitly set in California, which does not even require law school for someone to take the bar exam. In theory, Christy could have just stayed Steve's apprentice for seven years and she would have qualified to take the exam.
- Crosses the Line Twice: The "Why are you spitting on my husband's grave?" gag.
- "Funny Aneurysm" Moment: In episode 5 of season 1, Bonnie jokes about relapsing and that it was surely going to happen. Not only does she do relapse, but it happens to her twice.
- Family-Unfriendly Aesop: The episodes that dealt with Bonnie trying to help her brother stop doing drugs gives out two:
- When it comes to those with addictions, ultimately it's their choice whether they want to get clean or not. Even if friends and family want them to stop, they really can't force them.
- It's better to let go of those who choose to continue with their addiction for your own health and mentality.
- Funny Moments:
- In "Estrogen and a Hearty Breakfast," Bonnie, fearing she might be pregnant, goes to a clinic and gets an unflattering diagnosis.Bonnie: ARE YOU FREAKING KIDDING ME?! You are a lying SON OF A BITCH! You shouldn't even be aloud to practise in this country! [storms out of the clinic] "Menopause" my ass!!
- The look into Christy's train of thought when she tries meditation in "Big Floor Pillows and a Ball of Fire."Christy: (Thinking) Alright, here we go. Quiet the mind. Yepper-dee-doo. Why did I say that? That's not a quiet mind. Okay, here we go. Oh! Can't forget that eye appointment on Thursday. Grr, stop it! (beat) I come from a land down under! Where the Hell did that come from?
- In "Estrogen and a Hearty Breakfast," Bonnie, fearing she might be pregnant, goes to a clinic and gets an unflattering diagnosis.
- Harsher in Hindsight: A season 4 episode saw Christy date Marjorie's nephew Nick, who is played by Chris Pratt, Anna Faris' real life husband. Christy and Nick broke up at the episodes end, and several months later after the episode aired, Anna and Chris separated.
- Heartwarming Moments: The end of "Free Therapy and a Dead Lady's Yard Sale". Violet, having learned her birth father was abusive, asks Christy if she is a reminder of a dark period of her life. Christy assures her daughter it's just the opposite: Becoming pregnant with Violet gave her the courage to leave her boyfriend for good. It's the least hostile interaction Christy and Violet have ever had.
- Jerkass Woobie: Bonnie was abandoned by her mother, abused in foster care, went undiagnosed with ADD, abandoned by her daughter's father and spent two years being drugged without her consent.
- Squick: Christy and Patrick's whole relationship given that he's her future stepfather's brother and is now her uncle thanks to Bonnie and Adam tying the knot. On Patrick's part, it's also a little creepy that he's interested in someone literally introduced to him as his future sister-in-law's daughter.
- The Woobie:
- Christy. She grew up with an alcoholic and drug using mother in Bonnie and ends up following in her footsteps. At one point she was raped after taking too many drugs and has an emotional breakdown when she sees the rapist again. She was abused by Violet's father to the point that she ended up in the hospital. Her relationship with her children isn't the best, no matter how hard she tries.
- Jill during the anniversary of her mother's passing. She ends up getting depressed over the fact she's at the same age her mother was when she committed suicide and has nobody in her life to love. While it was never said outright, her behavior implied she was suicidal. She then attempts to fill the void by getting pregnant and was told she wouldn't be a good mother by Christy, which upsets her to the point of not speaking to Christy for weeks. And when she does get pregnant, she has a miscarriage.
- Tammy was unfairly kicked out of her foster home as a kid thanks to Bonnie, her father murdered her mother, and her Evil Aunt finally reunited with her only to take her kidney, wanting nothing else to do with her. She also has the worst luck: helping out a homeless guy cost her her job at a fast-food restaurant.
