So long Grey Sloan Memorial Hospital.

After ten drama filled seasons, the talented Sandra Oh departs Grey's Anatomy on the season finale tonight on ABC.

Dr. Cristina Yang's final appearance is in the episode entitled "Fear Of The Unknown" and although there are no spoilers, you can expect plenty of fireworks for the end of Season 10.

I have to admit that the first few years of the show, I was hooked! I gradually lost interest, but I know many people who have never stopped watching and are deeply bummed about Sandra Oh's exit.

As we bid her farewell, let's look back at some of Dr. Yang's best moments.
