Despite switching Sit Down, Shut Up out of Fox's main Sunday night animation block (relegating it to 6 p.m. CST) and only ordering five episodes of its first season, Fox didn't want to let sleeping dogs lie; instead, the network has declined to air the finale this Sunday, replacing it with a King Of The Hill rerun. And given the fact that Fox has yet to renew Mitch Hurwitz's new show, this is probably the end.
