Continuity mistake: At the bar, we see Mrs. Krabappel, and she disappears for the rest of the scene. (00:13:40)
Suggested correction: The place is crowded, she can easily be anywhere in the packed bar and simply out of sight.
Continuity mistake: When Skinner is set free, while holding onto the vacuum, he changes position between shots. (00:20:15)

Continuity mistake: John is wearing Homer's old "Pin-pals" bowling shirt when the Simpsons first meet him, but only after we see the back of the shirt does the name "Homer" appear over John's breast-pocket; clearly there was nothing there during their entire previous conversation.
