Much Apu About Nothing - S7-E23

Radio Bart - S3-E13
Continuity mistake: At the start of the scene where Bart talks to Rod and Todd on the radio, their shirt colors switch. (00:08:50)
Continuity mistake: When Homer laughs at Patty and Selma, for a few frames you can see that the beer can he was holding is gone. It stays beside the phone for the rest of the scene. (00:07:00)
Suggested correction: When Homer is laughing at Patty and Selma he never has the beer can in his hand. He has a drink then the camera cuts to Marge talking about Patty and Selma, Marge then walks out of the shot, and we get a close up of Patty and Selma. The shot then changes to Homer who starts laughing. Enough time to put the can down.
Continuity mistake: There are three mistakes when court is dismissed: 1) the people standing around disappear, 2) the two men with Fat Tony disappear for one shot, and 3) when Bart says that crime doesn't pay, Marge is suddenly standing beside Bart. (00:20:35)
Suggested correction: There are also 3 corrections here. 1) the only people standing near the bench are Lionel Hutz and Seymour Skinner. Seymour is simply out of shot and Hutz is on screen. 2) Legs and Louie don't disappear they remain standing on the steps but due to the camera angle that is now looking across the steps rather than up the steps so they are out of shot. 3) There is a close up of Bart and Fat Tony long enough for Marge to walk over.
Continuity mistake: When the mob is at the gates of Belle's house, the door bell is first seen on the left hand side of the gates. In the next shot (behind Flanders) it is in the center of the gates.

The Simpsons Christmas Special: Simpsons Roasting on an Open Fire - S1-E1
Continuity mistake: When Homer has been informed about the Christmas money being spent on Bart getting his tattoo surgically removed, he leaves the house.
