"Grey's Anatomy" is the longest-running scripted primetime show on ABC having been on the air since 2005.

In that time, it’s had 14 seasons, over 300 episodes, and eight major doctor deaths.

It's been a wild, sometimes devastating ride for fans — but they're still tuning in 13 years later.

According to Variety, a whopping 7.5 million viewers tuned in for the Season 14 finale, which bid farewell to longtime cast members Sarah Drew (April Kepner) and Jessica Capshaw (Arizona Robbins).

But even though fans have been watching for over a decade, and likely re-watching thanks to its presence on Netflix and status as a great binge-watching show, there's no way to know everything about the series.

Not even "Lexipedia" Grey herself could be expected to remember all of these surprising facts about "Grey's Anatomy."
