Programming advisory: HIMYM at 8 tonight, not 8:30

Just in case you don't have a DVR that automatically grabs new episodes of certain shows, note that tonight's episode of "How I Met Your Mother" is airing at 8 p.m., rather than 8:30 (when CBS is airing a rerun of last season's "The Bracket"). My guess is, with "Big Bang Theory" and "Two and a Half Men" already renewed for next year, and with a "HIMYM" renewal basically a sure thing, CBS is testing out how "HIMYM" does leading off the night, which it hasn't done in a while, to give them more options for figuring out next year's schedule.
