Apparently Sony's entry into the prime time animation wars didn't work out.
Fox yanks 'Sit Down, Shut Up' a week early
Fox ... opted to yank the remaining episode of "Sit Down, Shut Up" after the show posted a dismal 0.7 rating/3 share among adults 18-49.
... Fox will run a repeat "King of the Hill" in that slot.
Given "Sit Down's" perf, the animated half-hour is not expected to return.
I always feel bad for crews that work their tails off, only to see the gig go down in flames.
Sadly, these things happen ... and will continue to happen. What gets greenlit isn't always what has a life beyond its initial order.
