Yesterday marked an important date in pop culture history: it was the 20th anniversary of the premiere of Friends. And who better to celebrate and commemorate that day than one of the very friends on Friends, Courteney Cox? The actress appeared on Jimmy Kimmel Live—just a few short weeks after she participated in the mini Friends reunion with Jennifer Aniston and Lisa Kudrow on that very show—and she discussed the momentous day.

Cox, who looked classically chic in a long-sleeved LBD, told host Jimmy Kimmel that during the first year that Friends was on the air, the entire cast would watch together and that she would host. (Come on, of course Monica Geller herself would be the hostess!)

But the most important tidbit of their chat was when they discussed why viewers always wanted the famous "Rachel" cut, but no one ever asked for the "Monica." "You know, it kind of bums me out," she said. "Why didn't they? I mean we had the same hairdresser, I don't understand!" (We blame Phoebe and her infamous Dudley Moore/Demi Moore haircut mishap with Monica.) Turns out Cox had a very simple solution for her locks not being as famous as her pal Aniston's: "I just kept changing mine!"

Watch the full clip—in which Kimmel also breaks down the essential four claps in the Friends theme song—here:
