At the gathering in the beginning of this episode, Homer eventually gets drunk to the point of dancing on the couch with a lampshade on his head and saying "I'm the funniest guy in the world!" Reverend Lovejoy is sitting on the couch when Homer falls over and has his drink spilled on him. In the next shot where Marge looks irritated, Reverend Lovejoy is also in the background (somewhere besides sitting on the couch) looking shocked.
The morning after the party, an establishing shot of the Simpsons' house shows no cars outside. When Marge ushers Homer outside soon after to talk without the kids hearing, her station wagon is suddenly parked in the driveway.
Moe enters through the Simpsons' front door just after the Flanders, and stands with Homer while Ned talks about tending bar. The front door is still open. In the next shot, the door is closed and Moe has disappeared while Homer walks towards Ned.
