The Ultimate One-Off Simpsons Characters Quiz

There are dozens upon dozens of examples of people who turn up in The Simpsons' lives for about thirty minutes and are then never seen again. No one knows where they came from, no one knows where they go. We just know that, more often than not, they're hilarious.

Settle all these questions and more, as you embark upon this fiendish test that only true lovers of the show will ace.

Oh, and by the way, some of these characters do appear in other episodes, but only in the background or in non-speaking roles. Wikipedia counts them as one-off characters, so that's good enough for us.
