Some users commented that Jennifer obviously made certain choices as an actress, and that this was just the way her character reacted in scenes where Rachel felt particularly awkward about speaking up. However, a YouTube supercut posted in 2019 by a Friends fan appears to verify this was a habit that the performer leaned on more than just a few times.
The supercut is entitled, “Rachel Clears Her Throat 200 Times,” and while we did not count the number of throat clears to confirm the tally, we did give it a watch, and 200 does not appear to be much of a reach.
