You probably don't need us to tell you again, but we really are still obsessed with Friends. So when we're not lapping up details about the reunion episode, we're digging out fun facts from filming.
The latest one comes from Lisa Kudrow, who played Phoebe Buffay, who revealed the hilarious thing Jennifer Aniston, who played Rachel Green, always did on set.
During a recent interview with Variety's Actors on Actors, Lisa explained that she never watched Friends back, other than the bloopers - which is when she realised Jen was always guilty of laughing at Rachel's own jokes.
"This one time I was with Courteney [Cox], and we were trying to find something to reference, an old Friends thing," she explained. "And then we stumbled on – there's bloopers online – and we sat there at the computer like two nerds watching these bloopers laughing at ourselves."
She then went to explain how Jen would "get into these fits of laughter because you had this wonderful ability to – you were about to hit your punchline, and you would do this adorable thing where you would break.
"You would say the punchline, and you would always turn to the audience and say, 'I'm sorry, it's really funny'," Lisa recalled.
Sounds totally endearing and also very funny. You know a TV show is a good one if the actors are struggling to keep a straight face, right?
