“Don’t worry, I just drew up a little blueprint, now, lemme walk you through it.  This is the door, he goes through that.  This is the roof.  And this happy character here is the sun.  He shines down on the house, see?” – Homer Simpson

This post of storyboarding resources from Dakota State University contains a link to a sweet PDF from AnimationMeat.com that shows various animation layout techniques and shots with examples from the Simpsons.  Here’s a sample (click to embiggen):

If you’re at all interested in how the show gets animated or presented, this is a really interesting resource.  Even better, most of the example images appear to be from Seasons 7-9, before the show became the stale, digital waste we know today.  I saw sketches from “Summer of 4 Ft. 2”, “A Milhouse Divided”, “The Cartridge Family”, “Grade School Confidential”, “Homer’s Phobia”, and “The Old Man and the Lisa”, among others.
