Blackboard Joke: None
Couch Gag: Five capsules rest on the couch as Professor Frink walks into the room and places a drop of water on them, resulting in a replica of each family member instantly expanding from them. Frink then has to throw the rest of the pail of water on Homer's to expand it out to full size. (edit)

(over a walkie-talkie as Homer enters a restaurant)
Host: The pig is in the sty.
Cameraman: (sighs) You know, I used to make documentaries about coal miners, migrant workers--things that mattered.
Host: (impatiently) Yeah, yeah...we're all whores, just get in there. (edit) (Martin and Lisa are excavating for arrowheads.)
Martin: Care to make it a trio, Bart? You can brush and I can blow.
Bart: Well, I agree you blow.
Martin: Then it's a plan!
Bart: A lot of people blow, but no one blows like you.
Martin: High praise indeed!
Bart: When you look up "blow" in the dictionary--
Lisa: Bart, he's not gonna get it.
Bart: Fine. (edit) Bart: Usually when I do something bad, I feel good. But not this time. Martin was like Jesus... only real. (edit) Marge: I'd rather have a chubby hubby than a sexy exy! (edit) (Marge is suspicious of Homer, who is wearing a fedora hat and a trench coat.)
Marge: Homer, where are you going?
Homer: Work.
Marge: It's 4 o'clock on a Saturday.
Homer: I, uh, have to... count the atoms at the nuclear plant. Conservation of mass! It's the law! (edit) Lisa: Bart, Martin could be seriously hurt or worse! We have to do something!
Bart: You're right. Let's watch TV. (edit) Bart: (about a school assignment) The Internet wrote it, I just handed it in. (edit) Homer: Oh boy, dinner time! The perfect break between work and drunk! (edit)

The motel where Homer cheats on his diet is called the Sleep Eazy Motel. In season 9's "The Cartridge Family" Marge and the kids stayed at the same motel. (edit) The butterflies that Martin Prince raises are Monarch butterflies (Danaus Plexippus) (edit) Music From This Episode
"I Will Remember You" by Sarah McLachlan (Played during the video tribute to Martin.)
"Gonna Fly Now (Theme from Rocky)" by the DeEtta Little & Nelson Pigford (Played by the school's band at Martin's memorial.)
"Prelude in C Minor" for lute (BWV 999) by Johann Sebastian Bach (Performed on guitar and transposed to D minor; played on the Sanyo cassette player and by Nelson inside Martin's butterfly chamber.)
"Sabre Dance" by Aram Khachaturian (While Homer is getting amorous with the rotisserie meat.) (edit)

Puttin' on the Ritz
The restaurant where Homer is caught breaking his diet is called Pudding on the Ritz, a reference to the 1929 song and 1930 film of the same title Puttin' on the Ritz. (edit) Cheaters
The show Marge hires, Sneakers, is a takeoff of the syndicated show Cheaters and it's host Joey Greco. (edit) Bart: The bone's the very thing, methinks, to prank my sister and the dink.
Bart puts a twisted take on the famous line from Shakespeare's Hamlet, "the play's the thing wherein I'll catch the conscience of the King." (edit) NBC Mystery Movie
The conclusion of the episode mimics the title sequence of the 1970s NBC Mystery Movie (the figure with the flashlight) and mocks the series that were part of the movie (McCloud, Quincy, M.E., McMillan & Wife and Columbo). Also, Nelson's questioning mimics Peter Falk as Columbo. (edit) Dial M for Murder
The title of this episode is a play on the title of the 1954 Alfred Hitchcock film, Dial M for Murder. (edit)
