This is a list of episodes in which the ending credits vary in some way from the standard. That includes variations in music and backdrop, and dialogue that continues into the credits.

A few notes from Matt:
I've reorganized the list a little since taking over. The main groups are now audio, video, and Gracie/Fox; since numerous episodes fit more than one of these, use your browser's find function to search by p-code.
I've tried to verify every episode's credits, but there's always a possibility I missed something or made some other kind of mistake. Feel free to send me corrections and updates. There is also a list here of episodes whose credits I have yet to verify; they're probably standard, but any news on them is welcome. (Keep in mind that though certain things start before the credits, if something is contained entirely in the Executive Producers' screens, I won't include it.)
Also, careful readers might find that I've moved several clips out of the Fox logo section, because in every version I have seen they've been in the Gracie Films logo instead. Feel free to take up any beef with me, but I'd like some proof.

Readers might also be interested in Nicol�s Di Candia's recent "Treehouse of Horror" credits list here. It lists most of the spooky Halloween names taken on by cast and crew in those episodes.

Season 20 began (resurrected?) yet another trend: full credits with no interruptions or voiceovers for all episode premieres, special or not! However, repeats are sometimes cut off. As of 6/17/09, only those repeats since 2/1/09 (KABF18's third airing; its second was cut short, despite special music) have been full, with the exceptions of KABF19 on 2/8/09 and KABF21's third on 4/5/09.

(Note, please, that I did not pay as much attention when the text credits were introduced, or note how most special credits were treated between that time and the start of season 12. It looks like they came about during or just after season 9. I'd gladly accept, and give credit for, any information about those years.)

Starting with LABF01 in season 20, The Simpsons is being produced in 16:9 widescreen and HD. The credits still occupy the middle 4:3 area, presumably to allow a "safe" (ugh) space for pan and scan presentations. The Gracie logo, however, is stretched vertically; in the 4:3 episodes, it is at about a 2.35:1 theatrical ratio, letterboxed, but now it fills the 16:9 frame awkwardly. I see no need for this. The 20th Century Fox logo is the 16:9 version that basically includes the 4:3 one in the center.

Beginning with KABF22 (also the first episode broadcast in 2009), the show now uses a 4-act format, with the first act immediately following the opening. I'm not sure why. One assumes this will render the syndication break shuffle, noted below, a moot point (watch for scg-20). One is wrong (see scg-20). For Fox, LABF14 (Treehouse of Horror XX) is the sole exception so far, with three stories in three acts, and a long/special enough opening that it is on its own.

The following 52 episodes have no commercial break before the credits in syndication (instead keeping one after the opening). Seasons 17 to 19 have seen many more episodes join this list (though not always the best ones for it; see the SCG).
2F03, 3F03, 3F04, 3F06, 3F31, 3F17, 3F22, 4F03, 4F05, 3F24, 3G03, 4F11, 4F22 {js};
in season 17, GABF18, GABF19, GABF17, GABF20, GABF21, GABF22, HABF05, HABF06, HABF13;
in season 18, HABF21, HABF19, JABF02, JABF01, JABF03, JABF05, JABF04, JABF07, JABF09, JABF10, JABF11, JABF13, JABF12, JABF14, JABF15;
in season 19, JABF18; JABF19; JABF16; JABF22; JABF17; KABF01; KABF02; KABF03; KABF04; KABF06; KABF07; KABF10; KABF11; KABF12; KABF13.
Season 19 is the first in syndication to include Spanish voiceover credits, just before the production logos. For most of season 20, these extra credits are in the same font and color as the rest. See scg-19 and scg-20 for more.

On a related note, it seems that some alternate credits stemmed from the need to shift a break from before Act I to after Act III on Fox. Al Jean remarked in the 9F04 commentary that (because of the missing break after the intro) one more break was needed, and it was put before the credits; the cel was included so there was some "content," apparently to justify the credits' isolation instead of adding another act break. This probably explains 7G05, 7F04, and 8F02, and might have necessitated the song in 7G08. Oddly, 7G11 does not follow this pattern, but any information on this would be a help.
