This is from one of my fave episodes 'Hurricane Neddy'. Keep in mind that Springfield has had a hurricane and everyone's house is fine...except for the Flanders' house. The townspeople got together and tried to 'rebuild' the house. It was a disaster with a 'Load-bearing' Krusty the Clown poster, a 'floor' that was painted dirt, and a 'master bedroom' whose door you couldn't even crawl through. Then the house collaspses. Even Ned couldn't be nice through all of that.

Here's a longer clip. The sound quality isn't as good, though.
Thanks to this episode and my bookish nature, since my Dad saw it he's been calling me "The answer to the question I never asked" ever since. Thanks Dad...
