There was no tagline for this episode as it had a closing scene over the credits instead of the theme song.
After Luanne reads the card from Buckley she puts her hands down, and when she brings them up she has two Manger Babies on her hands. First, when she walks into the room the are clearly not on the ground, but even if they were she did not move enough to have put them on.
During the opening theme the "King of the Hill" sign appears above the guys as they are drinking, and the theme ends when Hank puts the trash in the garbage can, as suppose to its usually ending of his head and the title.
Dooley: (to Bobby) Your dad got blown up.
Luanne: I'm fine, aunt Peg. I broke up with Buckley just before it happened and never looked back. (pause) That's why I still have my eyebrows.
Luanne: Sock puppets are for babies. In the real world, beauty fades and penguins die a cold, horrible death.
Chuck Mangione: (while Mega-Lo-Mart survivors are undergoing therapy) Now Every song I play sounds like "Feels so Good."
Therapist: Maybe that's be cause it does "Feel so Good" to be alive.
Chuck Mangione: No, that's not it.
Hank: I did not blow up the Mega Lo Mart!
Buck: I'm glad you said that, Hank. I'm wearin' a wire for an unrelated matter.
(Showing a picture of Bobby in his underwear at Buckley's funeral)
Luanne: This is a picture of a starving Irish child. Fight the occupation! Fight the occupation!
Dale: So, Quincy, find anything yet?
Investigator: Not yet, sir.
Dale: Ha! That's what they want you to believe!
Investigator: Sir, we are 'they'.
The song Chuck Mangione plays at the funeral is "Feels So Good".
Although Buckley is dead, he remains in the opening credits every week, riding his motorcycle.
This episode was supposed to be scheduled on September 8. But it was postponed due to the Cubs vs. Cardinals baseball game on FOX.
Quincy: When Dale calls the man Quincy it is most likely an allusion to Dr. Quincy from the show Quincy M.E. who was a coroner.
"I think therefore I am"
Boomhauer changes up this famous Decarte quote when he says "I think therefore you are."
Boomhauer mentions the song Candle in the Wind. This is an Elton John song originally written for Marilyn Monroe after her death, and later redone for Princess Diana when she died.
"Death of a Salesman"
The title is a parody of the famous Tennesee Williams play.
Kahn: The more you hold in the more you put on strange Sinead O'Connor act!
Sinead O'Connor is an Irish rock star and activist. She's best known for revealing a photo of Pope John Paul II and tearing it in half after a rendition of her song "War" on an episode of "Saturday Night Live."
