Peter Digging Underground
Undergrounded is an episode of Family Guy.


Peter gets grounded by Lois after wasting his family's money via credit card, so be digs an underground escape tunnel, leading from his room to The Drunken Clam.


Lois Stupidly Doesn't Know Peter is Gone
Peter secretly gets a credit card after running out of cash at the Drunken Clam at the encouragement of the guys. After going on a spending spree, Lois grounds him for acting like a child. Desperate to escape the house, he builds a tunnel all the way to the Clam. When he shows off his handiwork to the guys, they end up trapped when the tunnel collapses.

Afraid that they may run out of air before being found, Peter confesses that their only hope is that Brian rats them out to Lois. The former lies to her about where Peter is, but tells Stewie who manages to trigger enough clues to locate them. While passing the time, they share secrets in their lives. The rescuers get them out and Lois rips into Peter for lying to her as he apologizes, but complains that she always treats him like a kid.

Trapped Underground
In a flashback of Peter's secret of Lois killing a person during their honeymoon 20 years previously to close the episode, they are in a seaside cafe and Peter selects the waitress for assassination because the chef says he can't make a chocolate chip & gumball pizza as Lois pulls out a gun and tells Peter that she loves him so much.

  • Cleveland has a secret mailbox kept from Donna at Mail Boxes Etc..
    • Joe also receives checks at Mail Boxes Etc and claims to have been on Seinfeld. Patrick Warburton played the role of "David Puddy" on the show.
  • This is the second consecutive episode to take a shot at Anne Hathaway, with Lois attacking Peter for comparing her to Anne in "Short Cuts", and Peter rejecting a chance to go see a film of hers with Lois and Tom Brady here.
  • As part of his escape plan, Peter hangs himself similarly to Brooks's death in The Shawshank Redemption. He did the same thing earlier in "Tiegs for Two".
  • The sign on the donkey at the Mexican doctor reads "Aborto Andale". This is supposed to mean "fast abortions", but ándale actually means "all right" or "come on!"
  • Cleveland reports that his 'uncle Reggie' was laid to rest, but when Peter digs his way up through the floor of the Drunken Clam, he apologizes for stuffing him in a garbage bag and dumping him in a pond.

Cultural References

  • Joe Cocker's "When the Night Comes" plays as Peter runs to Lois after being pulled from the tunnel.
  • Cleveland is a fan of Kid 'n Play; Joe likes Coldplay.
  • Meg mentions that Bad Moms and A Bad Moms Christmas, both starring her voice actor Mila Kunis, are available on streaming services.
  • Peter references Tina Fey's American Express commercials.
  • Patrick Star from SpongeBob SquarePants appears at the end of the episode, (voiced by his actual voice actor Bill Fagerbakke), narrating the story.
    • Patrick ending the story with "Everybody died" is a reference to a famous quote of his from the Spongebob episode, "Something Smells".
    • Patrick insulting the NFL is a reference to how fans of Spongebob signed a petition to have a song from Spongebob ("Sweet Victory") play during the 2019 superbowl to honor the life of show creator, Stephen Hillenburg, (who died a year prior), only for the NFL to play the fanfare intro of the song and then cut it short to feature some stupid rapper (Travis Scott) singing some shitty rap song. As you can guess, backlash from fans was unbridled and this is one of the instances of public outrage.
    • Patrick referring to his cussing as "Sailor Mouth" is a reference to the episode "Sailor Mouth", wherein Spongebob and Patrick start "cussing" (which is really just dolphin chirps, seal barks, boat foghorns, etc.) and they refer to the profanities as "Sailor Mouth".
    • Patrick telling the NFL to "Eat Sperm" is a reference to the episode "Chocolate With Nuts" and how during the episode, Patrick had a widely misheard line of dialogue, wherein he said "Please, spare me." which many have often misinterpereted as something along the lines of "Eat Sperm."
