The 34 Best ‘Grey’s Anatomy’ Episodes of All Time

*Warning: Spoilers ahead*

If you love Grey’s Anatomy as much as we do, you’ve probably seen all 19 seasons of the popular ABC series…multiple times. But with 420 episodes (and counting), there’s no denying that re-watching the show is a daunting task. That’s why we rounded up the 34 best Grey’s Anatomy episodes, so you can relive every heart-stopping moment in a back-to-back marathon. And by the time you've made it through these episodes, you'll be ready to dive right in to season 20, which premieres on ABC on March 14.

The cast hasn't revealed much about the plot for season 20, but we do know that the storylines will be "hot, unpredictable and compelling," according to Debbie Allen (aka Dr. Catherine Avery). She told ET, "It's going to be a shorter season because of the strike—we're only going to do 10 episodes—but we have a lot to look forward to… It's always brand new."

The actress also confirmed that Ellen Pompeo, who starred as Meredith Grey, will make an appearance. Allen added said, "The first episode is the one I'm going to direct, so she won't be too far. We have to let her go and do some other things, but she's still our queen. She's still our number one."

Given her many iconic moments in the series—from her heartfelt “Pick me. Choose me. Love me.” monologue to Derek to their decision to adopt—it's no wonder she remains a fan favorite. Keep reading for 34 of the best Grey’s Anatomy episodes, all available to stream on Hulu. (P.S., you can sign up for Hulu for just $8 a month, following a 30-day free trial.)
