Friends Reunion 2015: Ever since the friends on "Friends" last exited Central Perk, fans have been clamoring for a reunion. Sure, there have been dozens of min-reunions on shows like Matt LeBlanc's series "Episodes," and Lisa Kudrow's series, which analyzed Matthew Perry, but fans want a real "Friends" reunion on-screen. That might be tough since the cast members are too busy to reunite off-screen.

Courteney Cox, who played Monica on the iconic show, told Yahoo News that it's tough to get all six of them together in one place, even at Jennifer Aniston's wedding. Cox and Lisa Kudrow recently reunited to play Celebrity Name Game for host Craig Ferguson. That doesn't mean a Friends reunion will be happening, soon or ever. Cox said give up on it already.

"Dear lord, let it go people, we're not doing it! It's just not going to happen," Cox exclaimed.

"We've not really had a Friends reunion. We've gotten about 80 per cent there, but there's always one person who flakes at the end."

But which castmember is really to blame for the hold up?

"I'm not going to name names, but it may not be [David] Schwimmer," Cox said.

"Someone asks me every day [about a reunion]," Friends co-creator Marta Kauffman told Entertainment Weekly.

"I don't get upset. I understand that people want to relive that. But you can't relive that. We can't go back to that time in our lives. And I'd rather have people's memory of that be really wonderful than people going, 'Oh, he doesn't look good.' That would be bad. And let's be honest. Reunions generally suck."

So who needs the original cast? "Friends" fans found that they didn't even have to be united when they were shooting the original series.

Jennifer Aniston and Courteney Cox were secretly replaced by stand-ins where weren't supposed to make it to broadcast.  In Season 9, Episode 15, "The One with the Mugging"), not only did Rachel's stand-in appear in the middle of the friends' New York City apartment but she changed her shirt during the commercial break.

In the episode "The One With Rachel's Date," Season 8, Episode 5, Monica was replaced mid-sentence in the middle of a chat with Phoebe in the Central Perk coffee shop. Her stand-in didn't even bother to check her hair.

Thanks to the OCD of apparent math geek and Reddit user ASmileThatKills, we know how much money Joey owes Chandler. The question was asked in the Season 8 Episode "The One where Rachel is Late"

After adding up the costs of head shots, acting lessons, dancing lessons, voice coach sessions rent and utility bills and food expenses, ASmileThatKills' handy dandy calculator put the figure at $119,260.
