Somedays it might be Joey, then maybe Rachel - then it will switch to Monica. Basically we love them all.
FROM FRIENDS TO DESPERATE HOUSEWIVES: THE TV SHOWS THAT NEVER SHOULD HAVE ENDED
But Lisa Kudrow, who played Phoebe, had a favourite cast mate - Matthew Perry AKA Chandler.
She recently took part in a Reddit AMA, and said: "See now 20 people would be insulted. But, because I spent 10 years laughing hysterically at Matthew Perry off-set, it's Matthew Perry.
"And not laughing at him laughing with him, sorry!"
It seems, unlike us, Lisa has no problem picking her favourite anything from the series.
On the subject of her favourite episode, she said: "The Halloween party that Sean Penn appeared in. For lots of reasons.
"Number one it was the first show we shot after 9/11. And that whole week, while driving in LA, people would pull up, and give me a very sad look and a quiet 'thank you' for making them laugh."
While Lisa would love a reunion - just like every Friends fan in the world - she thinks the series ended at the right time.
She said: "It was great that we finished when we did, because I've loved everything I've done since."
