The Simpsons take a small step for cartoonkind and a giant leap for TV-dom when the town of Springfield legalizes gay marriage, perhaps for the dollars.("Them gay guys got lots of disposable income")
Hordes of like-bodied folks flock to Springfield, and are opposed only by the local Reverend, who refuses to hear the voice of reason, creating a business opportunity, taken advantage of by Homer.
One of the characters comes out of the closet, potentially gets corralled into something he/she didn't expect, but it all works out in the end. Homer gets ordained by a website-based operation that provides printable dogcollars, and gets a brainwave for a reality show which he pitches to Fox in a brilliant self-referential (same network) send-off.
If you're pitching a show where gold-digging skanks get what's coming to them, press 1;If you pitching a ripoff of another network's reality show, press 2, please stay on the line - your half-baked ideas are all we've got
The gay marriage issue, and other ideas are parodied well, if too briefly. The creators have promised to deal with these themes frankly going forward. In the next, bonus episode, Marge confronts Homer about his trove of erotic magazines, to humorous effect.
