Friends has become of one American TV's most iconic shows. And although we said goodbye to Ross, Monica, Rachel, Chandler Joey and Phoebe in 2004, the cast—sans Matthew Perry—reunited last month to film a special clip to celebrate the show's director, James Burrows, for Must See TV: An All-Star Tribute to James Burrows, airing tonight (February 21) on NBC.

With the special reunion airing this evening, we've put together a list of our favorite, most iconic moments from the long-running NBC sitcom. From the introduction of Phoebe's legendary folk song, "Smelly Cat," to the surefire "pivot" method of transporting a couch up a small stairwell, to Ross and Rachel's epic love story, here are 20 Friends moments we'll never forget.

And if you think we missed any, be sure to share your favorites in the comments.
