Do you remember The One where the two sisters fought over Ross on Friends?
If not Reese Witherspoon gave her millions of Instagram followers a reminder to let them know how much fun she's having working with Jennifer Aniston again.
The two chatted with Access Hollywood to reminisce playing the warring sisters on the US hit comedy show.
They also performed a short scene from one of the episodes where they played Rachel and Jill Green.
Reese posted: "One of the best parts of working with Jen is reliving my favorite lines from #FRIENDS! #theGreenSisters."
The pair look at a piece of paper with the Friends scene first.
Jennifer, 50, says: "This is where you say the line you love so much."
Reese asks: "Well, we could say the lines, do you remember your line?"
Making it clear she's forgotten her line, Jennifer replies: "Uh, uh, uh-uh. But you, you, umm."
Reese holds up the sheet of paper over their faces and Jennifer recalls: "I say, "You can't have Ross!"
Reese replies: "Can't have, can't have! The only thing I can't have is dairy!"
Reese also shows a picture of the sisters sitting on a sofa inside the Friends meet-up spot Central Perk where Rachel worked as a waitress in the earlier episodes.
Earlier this week Jennifer made her debut on Instagram by posting a Friends reunion picture.
She selected a selfie that showed her smiling alongside her Friends co-stars David Schwimmer, Courteney Cox, Lisa Kudrow, Matt LeBlanc and Matthew Perry - the first ever full reunion snap of the actors.
She added the playful option: "And now we’re Instagram FRIENDS too. HI INSTAGRAM."
Friend celebrated its 25th anniversary last month.
