Could this be one of the best-kept secrets in the history of Friends? Well apparently so – until now, that is.
Because over a decade after it first aired, an eagle-eyed fan has spotted a moment in an episode of the classic sitcom when Jennifer Aniston was replaced by a stand-in – except nobody actually noticed.
The moment, uncovered by one Jordan D’Amico – who happened to notice it during a routine viewing marathon – occurred during episode 209, The One With The Mugging, which was first shown in 2003.
As you can see from the evidence, Jen, as Rachel, is all present and correct at the start of the episode when Joey (Matt LeBlanc) rushes in to the apartment to reveal that he has an audition with actor Leonard Hayes (played by Jeff Goldblum)
