It ended 12 years ago, but we still just can't let go of one of the best sitcoms of all time.
Although everyone had their favourite friend, much of the shows brilliance is due to the huge host of celebrities that made cameos throughout the 10 seasons.
While we love the recurring characters like Paul Rudd's Mike or Tom Selleck's turn as Richard, this list is more concerned about the celebrities that only featured in one or two episodes, and there is no shortage to chose from.
Dakota Fanning
The One with Princess Consuela, Season 7
When Chandler and Monica bring Joey to view their new house, he meets the young girl who the house previously belonged to. Since Joey isn't the most mature of men, he and Mackenzie bond over their reluctance to change. The best part of this is probably when Chandler briefly convinces Joey that he was talking to a little ghost girl.

Julia Roberts
The One After the Superbowl: Part 2, Season 2
Roberts played Susie Moss, a girl that Chandler knew in the 4th grade, when they catch up after all those years Susie jokes about him pulling up her skirt when they were kids. We realise by the end of the episode that she never did get over that prank, and leaves Chandler in a restaurant toilet cubicle wearing her underwear to get him back. Julia Roberts and Mathew Perry were actually dating in real life when this was filmed.

Alec Baldwin
The One in Massapequa, Season 8
Baldwin plays Phoebe's boyfriend, Parker, who is definitely one of the most quotable guest stars on the list. Overly-enthusiastic Parker thinks everything is miraculous, wonderful and delightful. And that all moments are worthy of taking a mental picture - click.

Hugh Laurie
The One with Ross's wedding: part 2, Season 4
When Rachel makes a last minute decision to stop Ross and Emily's wedding, Hugh Laurie plays the unlucky man who is stuck beside Rachel on the flight. He inevitably has to listen to all the Ross and Rachel drama as a result, no matter how hard he tries to ignore it.

Stiller plays the hilariously angry Tommy, who is dating Rachel. However it is only ever Ross who witnesses him acting aggressive. The gang assume that Ross is just jealous of him seeing Rachel, until they all walk in on him screaming at the chick and duck.

Pretty much everything Danny Devito does is hilarious, but playing a stripper who borrowed his nephews halloween costume is definitely one of the best. When Monica and Rachel forget organise a hen party that is too tame for Phoebe, they book Roy, the stripper last minute.

Ryder plays Rachel's old sorority sister whom she bumps into at the coffee house. Rachel tells the group about how she and Melissa once shared a drunk, late night kiss, but when she asked Melissa about it, she denies it in front of Phoebe. Rachel, fed up with being called a liar, kisses her once more, and that's when we realise that Melissa is basically head-over-heals in love with her.

This was actually Lovitz' second appearance on the show, he played a very stoned food critic in season one. In this episode, Rachel goes on a blind date with Lovitz' character Steve, who is in short - a loser. Steve has some brilliant lines in this episode and Rachel's honesty about how badly the date is going makes it even funnier.

Bruce Willis plays the father of a girl Ross is dating. Elizabeth is quite young, which means that her dad is isn't a big fan of her older boyfriend. Willis' character begins dating Rachel, which means we get to know Paul over three episodes. Although he is extremely intimidating at first, Paul turns out to be a neat guy in the end.

Pitt was married to Jennifer Anniston during filming so it seemed funny at the time to have a story line about them hating each other (little did we know what the future held). He plays Will, who is an old school friend of Ross's and together, they formed an "I hate Rachel" club.

One of those brilliant random cameos that doesn't even tie into the story very much. When Monica attempts to tell the group about Pete's UFC dreams, she is interrupted by the drama going on between two men on the couch.

Joey gets his very own stalker in Erica Ford, who genuinely thinks he is his character from Days of Our Lives. Joey and friends of course decide to play along with the lie. Erica is probably best remembered for her terrifying cackle and her finger biting.

Right at the end of the scene above, Homer Simpson's voice actor plays a zookeeper who tells Ross that his monkey is still alive and that he has gone on to become a movie star.
