From The Hollywood Reporter:
"After two episodes, Fox is pulling Mitch Hurwitz's animated comedy Sit Down, Shut Up from its post-"Simpsons" slot Sunday nights.
Starting next week, "Sit Down" will air at 7 p.m. instead, a low-rated hour that's only considered "primetime" on Sundays. Repeats of "American Dad" will fill 7:30 p.m.
The remaining episodes of the final season of King of the Hill will ride to the rescue, filling the 8:30 p.m. slot. The rest of Fox's lineup remains unchanged.
