Many of you are probably aware of this already, but for those of you who aren't, ABC will be airing Grey's Anatomy episodes on Fridays at 8 p.m. EST.

That's in addition to the all-new episodes which air Thursdays at 9 p.m., giving people a chance to catch it if they missed it the first time, or watch it again if they're so inclined.

Or, in the case of our Canadian friends, watch the correct episode this time. Sorry. We couldn't pass that up.

Last week, Grey's Anatomy returned with its Season 3 premiere, "Time Has Come Today," and immediately proved it will be a force on Thursdays. Derek, Meredith, Cristina (pictured) & friends beat out CSI as the night's top-rated show, though CBS edged ABC for total viewers on the night.

Suffice it to say, those of us who haven't seen "I Am A Tree" are eagerly awaiting the chance to. We'll have a preview of it (without giving away any real spoilers, don't worry) later this week!
