Despite ending over 15 years ago, fans of the sitcom Friends just noticed something that happens in nearly every scene involving one of the show's main characters.

You may have noticed Jennifer Aniston's character, Rachel, clearing her throat in a couple of scenes, but you might not have realized how often it actually happens.

A viral TikTok claims Rachel actually clears her throat before almost every scene throughout the show's 10 seasons and it has caused quite the stir among fans.

“Jennifer Aniston has this sort of vocal tic that she does at the beginning of every single sentence that she starts,” says the TikToker, “It’s very specific and very hard to unsee once you notice it.”

A few of the hundreds of throat-clearing instances can be heard in the video below.

Some believe the habit is not that of Jennifer Aniston but instead is a part of her fictional character's identity.

Other eagle-eyed fans of the show claim to have known about the noise for a long time now, saying it's only done when the character feels uncomfortable.

One superfan claims to have even made the excessive throat clearing a part of a Friends-themed drinking game while in college.

Aniston has not replied to the recent discovery of the character's habit.
