Ever wonder what happened to Alison's sister and brother-in-law from "Knocked Up"? The dynamic duo of Debbie (Leslie Mann) and Pete (Paul Rudd) had a few key scenes in the film, including Debbie taking Alison (Katherine Heigl) to the club where she meets Seth Rogen's character.

Now Judd Apatow aims to brings us back into the lives of the couple as Debbie celebrates her 40th birthday in "This Is 40." Continually lying about her age as she refuses to accept it, Debbie wonders if she's living the best life possible and decides she and Pete need to make some changes.

"I've made a list," she tells her husband in a scene from the trailer, which was released on Friday (April 27). "It's the 'do-better' list. We're 40 years old, if we don't do it now, when are we going to do it?"

Read on for more on five key scenes from the clip!

Counting the Rings
At the gynecologist's office, the nurses try to figure out if Debbie was born in 1972, '74 or '75 since her paperwork lists a range of dates of birth. When Debbie finally blurts out, "I lie about my age, OK? OK?" her gynecologist responds, "I know how old you are. I'm counting the rings." And with that line, we know typical Apatow humor will be on display in this flick. After that exchange, Debbie decides it's time for a change and makes a list of the top three things she and her husband need to focus on now that they're in their 40s: exercise, the kids' education and being patient.

Exercise Every Day
In one scene, Debbie works with a personal trainer, which allows the filmmakers to bring back Jason Segel's "Knocked Up" character, also named Jason. "I can turn your body into a boner machine," he tells Debbie. When she points out that every woman gives him a boner, he replies, "Don't sell yourself short," before adding in a whisper, "Barb doesn't give me a boner." Looks like Jason's crush on Alison's sister never went away.

Get Involved in School
As Pete confronts a mother whose son is picking on his daughter, "Bridesmaids" star Melissa McCarthy makes a cameo as the confrontational mommy. She tells Pete to get his daughter's meds right and Pete calls her son an animal. When Pete gives her shoulder a little shove, she screams, "You touched my nipple!" When he tells her he merely touched her below her shoulder, she replies, "I have very high nipples!" How Rudd kept from breaking into laughter during that scene is beyond us.

More Patience With the Kids
Another key scene opens with Pete and Debbie's daughters pulling each other's hair as they fight in the back seat of the car. It then cuts to them at the dinner table, where Debbie announces they're cutting back on the girls' gadget use so they'll spend more time outside. She suggests instead that they build a fort, to which the exasperated eldest daughter exclaims, "And do what in the fort?" When Debbie says, "You don't need technology," the youngest daughter holds an iPhone up to her mouth and says, "No technology," as a monkey on the screen mimics her words.

Payback Time
The final scene shows Pete spread-eagle on a bed, holding a mirror up to his crotch trying to look at ... something. (We honestly don't want to know what.) When he asks Debbie to take a look, she asks if they can just keep a small shred of mystery in their relationship. Pete replies, "I saw you have babies — payback time." At least being in your 40s isn't boring.

"This Is 40" is set to hit theaters Christmas 2012.
