10 Biggest TV Show Blunders Ever

10. The One Where Everyone Has A Clone - Friends

The concept behind the sitcom Friends is pretty easy to grasp. We follow the trials and tribulations of a quirky group of friends: Ross, Rachel, Joey, Phoebe, Chandler, Monica, and of course, the seventh Friend: New York City.

Although the show was originally planned to be called Ross's Friends, the chemistry and comedy chops of the ensemble cast ensured that they all got equal screen time and storylines. This was a pretty sweet deal for the cast, especially considering the massive million dollar paychecks they were cashing per episode in the later seasons.

With this in mind, you would think there would never be any need for any of the actors to, say, leave work early and have a double stand in for them. Sitting in a café and chatting to your pretend pals can't be the most taxing task, especially when you know you've got a sweet millie waiting for you on the other end.

As you can see above, however, that is definitely not Monica talking to Phoebe. We don't know what happened to Courtney Cox that prevented her from shooting this scene, but the same thing must have been happening to Jennifer Aniston. In another episode, we can clearly see that Rachel has been replaced by someone completely different for all of Joey's close-ups.

For these Friends it was a case of "I'll be there for you... unless I can pay a struggling actor to stand in for me!"
