In the episode where Skinner almost marries Edna, Skinner confesses to Homer that he's getting cold feet. Homer then rushes home to tell Marge. First, we see the set-up shot, the outside of the Simpson home, with Homer's pink car parked in the driveway. Other than an oil puddle under one wheel, the car seems fine. A few seconds later, Marge complains that Homer is always finding new ways to annoy her. Homer denies this, then annoys her by asking if he can use her car because his is "acting up". We then see out the window that the pink car is on the lawn, overturned, in flames. How--and when--did that happen?
