During Sideshow Bob's and Edna Krabappel's date in the restaurant, one can see several portraits behind the booth where they are sitting; one of those portraits is of Birch Barlow, the radio talk show host who helps get Bob released from prison and later elected mayor, in episode 6x05 (#108) "Sideshow Bob Roberts."
A few scenes later, Bob & Cecil's wine glasses changed shape.
Bob: You again! Well, that's it. I'm going to do what I should have done a long time ago. (at the Simpson home, there is a knock at the door. Marge opens it and its Bob) Madam, your children are no more… (pause) … than a pair of ill-bred troublemakers.
Homer: Lisa too?
Bob: Especially Lisa. But, especially Bart.
Cecil: Hello, brother. All's well, I trust?
Bob: It most certainly is not. The workmen you've given me don't know their asses from the hole in the ground they blew up yesterday.
Cecil: Come now, you speak as if they were nothing but a gaggle of slack-jawed yokels.
Cletus: Mister Terwillidjer, come quick. There's trouble down to the See-Ment mixer, sir!
Bob: That was Edna Krabappel. You only get one chance with Edna Krabappel, I hope you're happy.
Bart: I won't be happy until I find out what you're up to. Wherever you go and whatever you do, I'll be there watching and waiting.
Wiggum: He says that, but I bet he gives up pretty quickly.
Cecil: There it is, the future site of the Springfield hydroelectric dam.
Sideshow Bob: Just the thought of all that raw power makes me wonder why the hell I should care.
Cecil: Because you'll be supervising the construction crew.
Sideshow Bob: Oh, great. I suppose that when a woman passes by, it will be my job to lead in the hooting. "Oh, yeah! Shake it, madam. Capital knockers!"
Krusty: (about Sideshow Bob) That guy's a genius! He's gonna change the way we think about getting hit by pies.
Lovejoy: Oh, that was lovely, Robert. You other cons could benefit from his example. (Inmates mutter angrily.)
Bob: Really, Reverend, your praise is going to get me beaten up.
Marge: Oh, you have nothing to worry about, honey.
Homer: Your mother's right, Bart. Sure, you're the one who ruined all of Sideshow Bob's criminal schemes…
Marge: We're very proud of you, by the way.
Homer: …and sure, he's probably so insane with rage that he'd butcher you horribly if he could.
Marge: But, he's safely locked away.
Homer: In a medium-security prison.
Marge: For life!
Homer: Unless he gets out somehow.
Marge: Which is impossible.
Homer: Or so you'd think! Except he's done it so many times before.
Sideshow Bob: Whenever I could find a spare moment I've tried to murder Bart Simpson.
(Bart shrieks in terror and runs away.)
Homer: He said "tried!"
Marge: Hmm, somebody should really go up there and talk to him!
(Lisa sighs and gets up)
Bart: Don't you see what you've done? Sideshow Bob hasn't reformed, he's pure evil. Oh, if only you knew what he was thinking!
Sideshow Bob's Brain: I hope they still make that shampoo I like ...
Krusty: (singing) I slugged some jerk in Tahoe,
they gave me one to three,
my high-priced lawyer sprung me,
on a technicality,
I'm just visiting Springfield Prison.
I get to sleep at home tonight.
(The prisoners are unimpressed)
Hey I kid! … I kid cause I love!
Cecil: At last, I get to do what Bob never could - kill Bart Simpson!
Bart: By throwing me off a cliff? Isn't that a little crude for a genius like you?
Cecil: Oh, I suppose it is. Heh. If anyone asks, I'll lie.
Sideshow Bob: You, saved my life, Bart.
Bart: Yeah, I guess this means you can't ever try to kill me again, huh?
Sideshow Bob: Oh, I don't know about that. Joking! Joking!
Sideshow Bob: I'm telling you Cecil, I can't take much more of this! Rustic workmen who've turned the saniJohn into a smokehouse! Coveralls that don't quite cover all! And a psychotic little boy who won't stop hounding me!
Bart: He's planning something evil, I know it. It must have something to do with the town's water supply.
Milhouse: Maybe he's gonna pee in the river!
Bart: Mmm, nah, that's not his style.
Sideshow Bob: You'll never get away with this!
Cecil: Who will the police believe did it? Me or the murderous, criminal mastermind?
Sideshow Bob: Now, I know Cousin Merle has a few problems, but he is not a--Oh. You were talking about me.
Lisa: Um, do you know what you're doing?
Sideshow Bob: Lisa, you don't spend ten years as a homicidal maniac without learning a few things about dynamite.
Sideshow Bob: Oh, come now! You wanted to be Krusty's sidekick since you were five! What about the buffoon lessons? The four years at Clown College?
Cecil: I'll thank you not to refer to Princeton that way.
Bart: And God bless Mom and Dad and Lisa and Maggie. And please, God, kill Sideshow Bob.
Marge: Bart, no!
Bart: It's him or me, O Lord.
Marge: You can't ask God to kill someone!
Homer: Yeah! You do your own dirty work!
Sideshow Bob: You do know I used to have a..."problem" with trying to kill people?
Cecil: (Sarcastically) Goodness, I had no idea. For, you see, I have been on Mars for the last decade. In a cave. With my eyes shut and my fingers in my ears.
Sideshow Bob: (Rolling eyes) Touchë.
Bart: Man, those cons love Krusty. Inside every hardened criminal beats the heart of a ten-year-old boy.
Lisa: And vice versa.
This episode was nominated for the 1997 Emmy Award for Outstanding Sound Mixing for a Comedy Series or a Special.
Both Pierce and Grammer play brothers Niles and Frasier Crane on the NBC series Frasier. The unseen character of Maris (Niles' wife) from that series is mentioned during this episode.
In addition to both characters appearing on Frasier and the refrence to Maris, the home of Cecil is almost identical to Frasier's on the show. There is a Frasier-style title card, and the banter between the two characters is exactly like the brothers on Frasier.
Blackboard Joke: None.
Couch Gag: The room is upside-down. The family runs in on the ceiling and sit down on the couch, until they fall to the "real" ground.
Another riff on John Sayles "The Brother from Another Planet" similar to "The Brother from the Same Planet," four seasons prior.
In the Krusty Prison Special Krusty's sings and dresses exactly like country music singer Johnny Cash, who is also known for performing in prison benefits.
Title Card: 'FRASIER' IS A HIT SHOW ON THE NBC TELEVISION NETWORK
The black title card with white text and jazzy music is a feature of the television series Frasier.
