When I first saw that, I laughed so hard at the time Bart swung around on the fan, and Homer said D'oh, and then again when Homer was screaming the gibberish as the bus drove away lol.
The first 10 seasons of The Simpsons are classics, the only bad episodes were the ones where they play repeat scenes from the earlier episodes, such as the paint your wagon and love times scenes.
Also, the April Fools prank Bart played on Homer (exploding beer can) was a classic until they started playing the earlier scenes again.
