Continuity mistake: As the nurse is talking to Susan about the operation, the folding of the paper the nurse is holding on the clipboard changes between shots. First it is half folded over, the next shot it has been folded right over and is being held right down. After this shot it changes again and is now folded back without her moving the paper.
Continuity mistake: When Carlos is about to be vaccinated, him and Gabby sit in the waiting room. Throughout their conversation watch Gabby's arms. At one point she has them down beside her, then in the next she has them folded. In the following shot they are down again, and in the next one they are folded.
Continuity mistake: In "Thank You So Much" Valentine's day was on a Saturday or Sunday. In this episode, They are showing Bree marking her chores off a calendar for February and March 2006. The calendar matches the real calendar and Valentine's day was a Tuesday this year. The calendar doesn't match their previous episode. And they do state that "today is Valentine's day." not that they are celebrating it on the weekend.
Continuity mistake: When Gabby first goes to visit Carlos in prison, they sit down at a table. Watch Gabby's arms. At one point, she folds her arms, yet in the next shot they are on the table. In the next shot they are folded, and in the one after that they are back on the table.
Continuity mistake: In the episode where Gabby kisses Tom Scavo and, in return, Lynette kisses Carlos, Gabby is making a smoothie. When she's drinking it (as Lynette and Carlos are making out), it keeps switching from her left hand to her right hand, depending on which angle the camera is facing her.
Continuity mistake: Lynette goes to her second interview and has to take her daughter with her. When she is talking to Stu the receptionist he is eating a long sandwich. In the initial shots the sandwich is whole, but by the final cut away the sandwich has been cut in half lengthways, with the second half now on the desk in front of him.
