10 Times The Cast Of Friends Have Reunited

Schwimmer appeared in Episodes alongside the series' star Matt Le Blanc. Schwimmer, who like Le Blanc was playing a version of himself, bumped into Matt at the party of a dangerous but very wealthy dictator.

Le Blanc - who played eternal bachelor Joey Tribianni in the long-running sitcom - hasn't shied away from guest starring in his former co-stars shows himself. He joined forces with Lisa Kudrow for a stint on the actress's comedy series Web Therapy, playing a patient with a gambling problem.

Courteney Cox - best known for playing high-maintenance chef Monica Gellar - has also made an appearance on Web Therapy. During the first series she turned up as troubled psychic Serena Duvall who loses her ability to interpret her dreams and contacts Fiona for advice.

David Schwimmer was another Friend to brave Fiona's Skype sessions. He played Newell Miller - another patient who dared to face the straight-talking therapist in series two. If Ross Geller was adorably awkward, Schwimmer's Web Therapy character is borderline creepy as he recalls witnessing his father's affair with Wallace and its scarring effects on his sex life...

Courteney Cox and Matthew Perry combined to play one of TV's best-loved couples as friends-turned-lovers Monica and Chandler. To the delight of their fans, the pair joined forces for an episode of the Perry's comedy series Go On, a show about slick-talking sports talk radio host Ryan King who is trying to move on with his life after his wife Janie is killed in a car accident. His former co-star played a potential love interest...

Perry then returned the favour and starred in Cox's show Cougar Town as a millionaire who popped the question...

Lisa Kudrow has also cropped up in Cox's sitcom, this time channelling her darker side when she appeared as a dermatologist with a mean streak on series one of the Florida-based series. Here she is cutting Cox's character Jules down to size in the waiting room...

Courteney Cox and Jennifer Aniston are known to be as friendly off-screen as they were playing Monica and Rachel so it came as no surprise when Aniston appeared on not one but two of Cox's TV series. Here she is guest-starring in Cougar Town as Glenn, a therapist who Cox's highly-strung character Jules visits for advice...

The pair got closer than ever before when Jennifer played Tina Harrod, a gay editor of a competing gossip magazine to Cox's character Lucy Spiller's in Dirt, sharing a blink-and-you'll-miss it smacker on the lips

Actor James Michael Tyler also guest-starred in Episodes. After being tasked with recruiting one of his former Friends co-stars to appear, Matt embarked upon a series of awkward phonecalls, only to discover that he had offended all five actors who now refuse to work with him. Gunther who saves his bacon, agreeing to guest-star as an ice hockey coach in their place...
