Before Kimmy and her friends leave us for good, scroll down to see 40 celebrity appearances on "Unbreakable Kimmy Schmidt" that are still making us laugh.
Jon Hamm appears in 11 episodes as "Reverend" Richard Wayne Gary Wayne, Kimmys kidnapper.
For almost the entirety of season one, The Reverend's face was kept obscured, leading fans to wonder what iconic actor Tina Fey had surely cast as Kimmy's kidnapper/cult leader/husband.
Hamm immediately showed off his comedic chops when he appeared towards the end of season one, and has periodically popped up to cause trouble in Kimmy's life.
Show co-creator Tina Fey plays two separate characters: Marcia and Andrea.
In season one, Fey first shows up as Marcia Clark, one of Kimmy's inept lawyers (a clear reference to OJ Simpson prosecutor Marcia Clark, perm and all ) in her trial against the Reverend.
Fey later reappears in season two as an alcoholic therapist, Andrea, that Kimmy starts seeing. The two work together to deal with their respective issues: Andrea's alcoholism and Kimmy's issues regarding her captivity and kidnapping.
Greg Kinnear plays himself in season four, and helps Titus impress his ex-boyfriend Mikey.

Lisa Kudrow plays Kimmys absentee mom Lori-Anne.
Kimmy's mother Lori-Anne was only alluded to for two seasons before we were introduced to her in the second season finale.
Lori-Anne and Kimmy reconcile their very tense relationship while screaming their heads off on roller coasters at Universal Studios: turns out Lori-Anne is a "coaster head," aka a roller coaster enthusiast.
Fred Armisen sporadically appears as Lillians ex-boyfriend, Robert "Bobby" Durst yes, that Robert Durst.
Lillian vaguely references her first love "Little Bobby Durst" before we finally meet him in the season two premiere. He continues to show up in random episodes before Lillian breaks up with him so she can run for office.
Little Bobby Durst refers to real-life accused murderer Robert Durst, star of HBO's true crime documentary "The Jinx," in which Durst appears to confess to "killing them all" (the three murders he's been connected with in the past).
Durst was acquitted of killing his elderly neighbor Morris Black. However, he was arrested in 2015, the day that the finale of "The Jinx" aired, charged with the murder of his friend Susan Berman. His trial is currently set for September 2019 .
Maya Rudolph shows off her impression skills when she portrays "Thats What Friends are For" singer Dionne Warwick.
Titus' time on a cruise ship in between seasons two and three was a big mystery for most of season three, until he reveals that he poisoned the iconic singer Dionne Warwick, played by Rudolph, so he could fill in for her.
Andy Cohen guest-stars as himself in season three.
It was only a matter of time before Jacqueline was approached about joining the cast of "Real Housewives of New York." The Bravo king himself asked her.
Jeff Goldblum plays a Dr. Phil-esque television personality, Dr. Dave.
Goldblum did a pitch-perfect impression of all the therapy/entertainment personalities out there, like Dr. Phil, Dr. Drew, and Dr. Oz, poking fun at the entire genre for being exploitative of victims.
Dr. Dave is introduced when one of Kimmy's bunker-mates, Cyndee, admits she's in therapy on national TV, with Dr. Dave.
Busy Philipps plays Sheba, the daughter of Lillians boyfriend Artie.
When Artie, Lillian's boyfriend, suddenly dies between seasons three and four, viewers were wondering if we'd ever meet his family. In the finale, Lillian meets his daughter Sheba who turns out to be the black sheep of the family.
Joshua Jackson gets to reference his "Dawsons Creek" past when he shows up as a cashier named Purvis in season two.
When Kimmy and her classmate Dong decide to go on a romantic trip together, they end up in a convenience store staffed by none other than Jackson, aka eternal heartthrob Pacey from "Dawson's Creek."
Jackson clearly has fun with all the "Dawson's Creek" references he gets to make, and shuts down any Team Dawson fans once and for all.
Laura Dern plays Wendy, a woman who begs Kimmy to divorce the Reverend, so she can marry him.
Wendy wants to marry the Reverend, who kidnapped three girls and one adult woman and kept them in a bunker for years. Kimmy decides to stay married to him in order to prevent Wendy from getting hurt.

Early in season one, Kimmy is pressured by Jacqueline to remove her "scream lines" with the help of plastic surgery. Kimmy even accompanies Jacqueline to her plastic surgeon's office.
Dr. Frampf has had so much surgery and Botox that he barely resembles a human being, which causes Kimmy to back out of the procedure.

David Cross plays a pre-facial reconstruction surgery Russ, Jacquelines boyfriend.
In season two, Jacqueline decides to stop caring about appearances and starts dating Russ, a nerdy, awkward lawyer. The two fall in love, but eventually break up after Russ is hit by a car, and has surgery that makes him much more conventionally handsome (more on that later).
A pre-"Chilling Adventures of Sabrina" Kiernan Shipka plays Kimmys half-sister, Kymmi.
While Kimmy was in the bunker, her mother married the lead detective on the case, and they had a daughter together named Kymmi, who resents her older sister for stealing all the attention.
"Hamilton" star Daveed Diggs plays Perry, one of Kimmys classmates at Columbia.
Diggs appears in three episodes as a friend (and potential love interest) of Kimmy's at Columbia. While Diggs is an extremely skilled rapper, Perry's bars leave something to be desired.

Jacqueline's boyfriend Russ was continually bullied by his brothers, including Duke.

Moynihan first pops up during the true crime documentary parody episode, "Party Monster: Scratching the Surface," which was about a DJ trying to uncover the truth about the Reverend.

Aidy Bryant appears as Tabby Bobatti, who was the Reverends girlfriend at the same time as he was keeping the women in his bunker.
The explanation that Bobatti saw the captive women in the bunker, but was told they were just "Victorian ghosts" is an all-time favorite "Kimmy Schmidt" joke.

Zosia Mamet plays Sue Thompsteen, one of the hated hipsters infiltrating the neighborhood.
Hipsters are just another New York City staple that "Unbreakable Kimmy Schmidt" skewers, and Mamet, of "Girls" fame, is the perfect choice to play Sue, who rents out Kimmy and Titus' apartment on Airbnb while on vacation.
Billy Magnussen takes over for David Cross as Russ after undergoing facial reconstruction surgery after a car accident.
Unfortunately, after Russ becomes handsome, he chooses his terrible family over Jacqueline (they had been fighting over the name of his family's football team, the Washington Redskins, as Jacqueline is Native American) and the two break up.
When Titus boyfriend reveals his baby daughter is named Linda, Titus seeks the help of other Lindas, like Linda P., played by Andrea Martin.
