What we're watching: The World Series takes a break as things change scene to St. Louis, and programming goes back to normal for one night. T.O. is on prime time as the Giants take on the Cowboys, and #81 always delivers on Monday Night Football. Otherwise, if the Heroes marathon last night piqued your appetite, it's back with a brand new episode.

Our traditional high-def listings continue below.
