10 Friends mistakes you probably missed

Finding and pointing out movie and TV mistakes is one of the more socially acceptable forms of schadenfreude. While those mistakes are rarely enough to derail the story or one's suspension of disbelief, it's perhaps comforting to know that even multimillion-dollar operations mess up sometimes (TV shows, they're just like us!).

This would make Friends, apparently, the most comforting TV show out there. With data culled from the goof-tracking website moviemistakes.com, MyLotto24 found that, on average, Friends had more mistakes per season — 149! — than any other TV show (at least within the available data). We've rounded up 10 such instances that probably escaped your notice on first watch (or subsequent watches, for that matter). Read on to never be able to not notice them again.

"The Last One" (Season 10, Episode 18)

To begin at the end, let's take a look at Phoebe (Lisa Kudrow) and Ross' (David Schwimmer) climactic rush to the airport to catch Rachel (Jennifer Aniston) in the series finale. Some extras standing behind the pair at JFK (note the headscarf) also appeared behind Rachel when the episode cut to her at Newark Airport. If only Phoebe and Ross could have teleported that easily.

"The One With All the Wedding Dresses" (Season 4, Episode 20)

The writing on Chandler (Matthew Perry) and Joey's (Matt LeBlanc) Magna Doodle changed across cuts, perhaps to reflect what politeness forbade them from telling Ross.

"The One in Vegas" (Season 5, Episode 23)

Perhaps this episode's editor had a keen sense of irony: As Joey told Chandler about his "hand twin," he pointed at Chandler with his left hand, which switched to his right hand in the next shot.

"The One With George Stephanopoulos" (Season 1, Episode 4)

In this early installment, Ross, Chandler, and Joey attended a hockey game, where Ross wore a foam finger that later disappeared. That's unfortunate for Ross, as the finger could have cushioned the blow of the puck that hit him in the face later in the episode.

"The One Where Ross Finds Out" (Season 2, Episode 7)

As Rachel learned that Ross and his girlfriend Julie (Lauren Tom) were getting a cat together, her necklace appeared and disappeared across cuts. Perhaps this was meant to symbolize Rachel's roiling inner turmoil as she struggled to suppress her feelings for Ross. (But probably not.)

"The One With Rachel's Date" (Season 8, Episode 5)

Ah, the perils of our transition to widescreen TVs. Here, the edges of the frame — which were cropped out when Friends originally aired — reveal Courteney Cox's stand-in taking her place.

"The One With the Mugging" (Season 9, Episode 15)

This episode is rife with errors, with another glimpse of a stand-in along with bottles changing to cans in Joey's hands. (He was raiding Chandler and Monica's apartment for something to drink for an audition.) Maybe Joey had unknown talent as a magician the whole time.

"The One With Rachel's Inadvertent Kiss" (Season 5, Episode 17)

More evidence for the Joey the Magician theory: His purple button-up shirt changed to a black zip-up top in the time it took for Ross to open his door.

"The One With the Red Sweater" (Season 8, Episode 2)

After Monica unwrapped one of her wedding presents, the gift was wrapped again in a later shot, as if it was trying to resist being opened without Chandler being there. Alas, she opened all the presents without him.
