...tune into FOX at 9:30 as the network begins a three-week run of FX's "It's Always Sunny in Philadelphia". They'll be airing three episodes from last season as they try to develop an audience for the new season, which begins on FX the week after the last rerun. The post-"Family Guy" timeslot should get the show about 3 times as many people tuning in than were before. Hopefully it translates into some real ratings success for the new season. It strikes me as a polarizing show, to be sure - you'll either really, really love it or really, really hate it.
At least it doesn't conflict with "Entourage" - no excuses there.
That show really grew on me last year, and this year (with Danny Devito) looks especially funny. The promos ("you're banging your sister?") are killing me this season, and I'm really looking forward to this season.
