Corrected entry: After Juanita is hit by the car, Bree, Lynette, and Susan are scrubbing the street. Lynette gets angry at a car speeding by them, and says "I have four kids" - but she doesn't, she only has three at this point. (00:04:17)
Corrected entry: When Mary Alice commits suicide at the start of the episode, she shoots herself in the right side of her head, but when Martha looks through the window and sees Mary Alice dead, she is lying on the floor and blood is coming out of the left side of her head.
Correction: So the bullet entered the right side and exited the left side.
When we see Mary Alice's body on the floor, there is no gunshot wound on her right side. So even though the bullet could have exited her left side, the lack of a wound on her right side is still a mistake.
There Won't Be Trumpets - S1-E17
Corrected entry: When Bree and Lynette are walking to Juanita's funeral, Bree says "You have to hand it to Gabi and Carlos. They do grief better than anyone." However, her mouth doesn't say Gabi and Carlos. This is because they originally said "You have to hand it to Catholics. They do grief better than anyone." But due to the death of the pope it was dubbed.
Correction: I do believe this only happens in some versions of it - maybe certain places/times that it was aired. The version I have, she still says "the Catholics".
Every Day a Little Death - S1-E12
Corrected entry: Lynette's children are at home during the poker game, which we later learn takes place every week on Tuesday at lunch. So the three school-age children should be at school. Even if there's a good reason for one school to have a day off, the twins are at a different school from their brother, and the two schools coincidentally having the same random day off is so unlikely as to be Impossible, unless commented on in the script.
Correction: It is not Impossible for the two schools to have the same day off. It could either be early dismissal for parent-teacher conferences, or a teachers in service day, which coincide for the whole district because of the bussing system. It could even be spring break.
Corrected entry: In the pilot the front door of Mike's house is different from his front door in later episodes.
Correction: People do sometimes buy a new front door without making a big deal about it. They don't have to put in a scene like "Look honey, what do you think of the new front door I put in yesterday?" for every prop that changes.
Love Is in the Air (a.k.a. What I Did for Love) - S1-E14
Corrected entry: Remember in the earlier episodes where Paul destroys the pool to retrieve the toy chest? Since the pool is now destroyed and barely fixable, how did Zach have the pool party? And we can see on other episodes the pool is perfectly fine.
Correction: The pool wasn't completely destroyed, he just broke into the bottom of the pool to get the chest. To keep up the appearance that nothing unusual happened, Paul would have to fix the pool so that no one would notice a difference.
Corrected entry: Mrs. Huber's "missing" posters state she died in Mid-December 2004. In the episode where she dies, the trees have green leaves, and the flowerbeds are full of colourful flowers.
Correction: Wisteria Lane is obviously in a part of the country that does not get cold in the winter.
Correction: Lynette does in fact have 4 kids at this point. She has 4 kids from the beginning of the show.
