Ned 'N Edna's Blend/References

Trivia
The thing inside the Scratchy costume in the video for Itchy & Scratchy weddings is obviously not a person. Homer's tweet seen during the episode, "ARE YOU SUPPOSED TO EAT THOSE STICKERS ON APPLES? I’M GUESSING YES.", was tweeted by the real world HomerJSimpson account during the episode's original broadcast.[1] This episode was previously known as "Ned 'n' Edna's Blend Agenda". Someone greatly resembling Mr. Becker appears at Marge's party.
 * God last struck Homer with lightning as punishment in Pray Anything.
 * The last time a Simpson portrayed Jesus occurred in Simpson Christmas Stories.
 * Ned's parents last appeared in Hurricane Neddy. This is their first appearance in present day Springfield.
 * The last time a fantasy sequence where things of Ned's chagrin actually happen, especially concerning his sons, was in "A Star Is Born-Again".
 * The last time Rod and Todd considered calling adults by their first names impolite was in Children of a Lesser Clod.
 * Bart previously annoyed Homer by calling him by his first name in Lisa's First Word.
 * Ned's nightmare is a parody of David and Goliath. David and Goliath was previously parodied in Simpsons Bible Stories and HOMЯ.
 * The last time Ned acted intolerant towards a moral woman's treatment of his children occurred in Bart Has Two Mommies.
 * The joke with the left gifted bidexterous and transhanded community's anagram is Lesbian, Gay, Bisexual and Transexual.
 * The chalkboard gag, "Call your mother during the commercials", refers to the episode's having originally aired on Mother's Day.

Continuity Errors

 * In this episode, Rod and Todd are already students at the Onward Christian Schoolboys Academy, while Ned is opposed to them attending Springfield Elementary. However, Rod and Todd have made a few cameos at the school (including Lisa's band class), while Ned is a member of the PTA and has held Junior Campers meetings there.

Continuity
Chazz Busby returns as the director of the passion play *Smoke on the Daughter "Everyone Loves Ned Flanders", which plays during the closing credits, was previously used as the theme song for The Adventures of Ned Flanders in "The Front". Ned's parents last appeared in "Hurricane Neddy". However, Mona Flanders first appeared in "Lisa's First Word". She looked totally different to what she does now, had crazy hair and seemed like a different person, in what is a horrible lack of continuity. Ned thinks that a talking dog is the work of the devil. In "Bart the Lover", Todd thinks that a talking dog is blasphemous

Goofs
Marge's face error. Edna pulls Rod and Todd out of a Christian school and puts them in Springfield Elementary. The Flanders family seems to act as that Rod and Todd are newcomers to Springfield Elementary, however, they have been seen at the school in previous episodes. These previous school cameos are probably the goofs, not this one. Large crowd scenes like that usually have many cameos, often by people who wouldn't usually be in the scene. They have, however, been seen at the school in more prominent roles in episodes such as "Bart the Daredevil" and "Skinner's Sense of Snow". In Fête Accompli, where there is a stand with videos of Extreme Weddings, in the middle there is a Zero-G wedding. Later on where Marge and Lisa look at the stand, Zero-G has been replaced with a video of an Itchy and Scratchy wedding, with the title of the video on the stand changing as well. An employee could have changed the video and title. Lisa and Marge could have looked at a different stand. If the display was automated, the screen could simply have switched to showing a different wedding. This can be done using presentation software such as PowerPoint. However, the title changed as well. In the scene where Marge is telling Helen about the canapes, her mouth disappears for a frame. During the Passion Play, Hans Moleman is seen in the audience. He is then seen on a cross to the left of Homer.
