I also found this to be a very enjoyable episode. And
I saw the whole thing.
It starts when Homer plugs in a dancing Santa and causes a citywide blackout, during which looting occurs (a man throws a cinderblock through the window of Cinderblock world and people steal cinderblocks; People break into King Toot's and march out playing the Notre Dame Fight Song) and the Springfield Police Force's ineptitude is made glaringly obvious. Homer then forms SpringShield with Lenny and Carl. Mayor Quimby tries to show the press that the police are still the most effective crime fighters in the city, but when they enter the police station, Chief Wiggum is blindfolded, trying to shoot a pinata (I don't know how to do the n with the ~) with a shotgun. The mayor then fires the entire police force makes SpringShield the official police. Then stuff happens and the Mafia tries to kill Homer.
The scene with the Mafia in the van was a spoof on "The Sopranos". The song in the background was the "Sopranos" theme.
(The family sits on the roof, watching the riot.)
Bart: Look at that! Looting, fires, destruction! They're living
my dream, and you won't let me join them!
(A police car shows up at the riot.)
Wiggum: (over bullhorn) Alright, disperse, people! We are prepared to use force! What's that, Lou? We're
not prepared? (The crowd attacks the car) Aah! Help! Call 911!
Lou: (over bullhorn) Aw, they never come.
(The next day in the living room.)
Marge: This is all your fault, Homer.
Homer: I know. I shouldn't have plugged in that dancing Santa. But I won't rest until I can put a human face on this!
(Lisa runs in crying.)
Lisa: Mom! Dad! Someone stole my Malibu Stacy collection!
Homer: Marge, does Lisa have a human face?
Marge: Yes, and it's crying, Homer.
(Homer, at the Wooly Bully, the store that a purple wool cap he found in Lisa's room came from.)
Homer: Do you sell caps?
Beatnik Clerk: Yeah.
Homer: To people?
Beatnik Clerk: Sometimes.
Homer: People with heads?
Beatnik Clerk: Occasionally.
(The "Dragnet" theme plays)
(The family eats breakfast in the kitchen, while listening to the radio.)
Marty: And now, we have local gangster, Fat Tony, with a message to Homer Simpson.
Tony: Yes, I would like for the town to know that my associates and I will gun down Homer Simpson at noon tomorrow if he has not left town by that time.
Marty: Great! Do you have a song request?
Tony: "Radar Love."
Homer: Ooh, I love this song!
(At the chuch, Homer tries to rally support after the Mafia threatens to kill him)
Homer: Come on! Who's with me?
Ned: I'm with you, Homer!
Homer: Shut up Flanders. Anybody at all? Docter Hibbert?
Hibbert: Gee, I'd like to help you, Homer, but I've got too much to live for. (chuckles)
Homer: Barney?
Barney: Sorry, Homer, but I'm a coward now, as are all recovering alcoholics.
(Tony's friends show up, consisting of several gangsters seen in the "Krusty's Daughter" episode.)
Tony: Ah, my Jersey muscle. Johnny Tightlips, how are you?
Johnny: I ain't sayin' nothin'.
Tony: Wonderful. How is your mother?
Johnny: Who says I got a motha'?
Tony: Very well. Let's roll, boys.
Marge: You can't kill my husband! Don't you see you're just perpetuating an Italian-American stereotype? Why, you could be a pizza man, an organ grinder, a... a leaning-tower builder... umm... did I mention pizza man?
Tony: (crying) You are listing all my shattered dreams.
(Homer confronts the Mob.)
Homer: You can kill me, but somebody will take my place. If you kill him, somebody'll take
his place. And it pretty much stops there. after that, the city is yours, really.
Tony: Okay.
Tony: Johnny Tightlips! Did you see the shooter?
Johnny: I see a lotta things.
Tony: You know, you
could be a little more helpful.

Some great quotes, funny sight gags. An extremely hilarious scene where Homer literally takes two to three minutes to rattle off a list of all the jobs he's ever had in the show's history, all while Marge is doing various things.
