Okay, here's what I suggest we all do about last night's KING OF THE HILL:
Call 310-369-3066.
That's Fox's number for "viewer comments" (you just leave a message, so calling after 6:00 is not a problem). Say as calmly as possible under the circumstances that only the last 5 minutes or so of last night's episode were shown, and you want them to reschedule the episode so you can actually see it. I think this is more effective than email, and if they get enough of these messages it might convince them to reschedule the episode.
Otherwise it might not be shown until next Christmas. I'm quite serious. One time a KotH Thanksgiving episode was pre-empted by football, and it was never seen again until a year later.
