[Warning: If the Grey’s Anatomy season finale sits unwatched on your DVR this morning, you might want to skip this spoiler-containing item.]

So I’m in shock about Grey’s Anatomy — and not the fact that Meredith did the dirrty last night with McCheaty (blech!) — but rather by ABC’s crazy masterful aggressive decision to move its hit medical drama to the Thursday 9 p.m. timeslot come fall. This sets up an epic battle between CBS’ big man on campus CSI, NBC’s promising freshman Studio 60 on the Sunset Strip, and Grey’s (plus, quite possibly, Fox’s Mischa Barton-free version of The O.C.). I’m going to have to give it some serious thought, but my gut says I’ll probably tape Studio 60 while watching Grey’s live. As for CSI, it’ll be reserved for those nights when my brain’s hurting and needs to go on autopilot. But that’s just me. Which Thursday 9 p.m. show will you watch live, PopWatcher? Which will you tape? Or are you more likely to experience total emotional shutdown and end up watching Internet footage of Dalmatians riding bicycles? Holla back!
