Friends promotional poster (Image via HBO Max)What makes Friends such an epic show is the cast, their chemistry together, and their ability to add their own inputs to the show. Though it has been on air for 25 years now, it almost feels like a show from today.Though there is no doubt that the Friends script is one of the wittiest in sitcom history, many memorable moments were improvised and unscripted. This is what makes the sitcom iconic.Top 5 unscripted moments from FriendsHere are five fan-favorite improvised and unscripted Friends moments that were retained on the show.1) Ben and Ross prank RachelJennifer Aniston Online@JenniferAOnlineRoss & Ben pranking Rachel will forever be one of my favourite #Friends moments primarily because Jen’s reactions are real as she didn’t know about the prank 06:18 AM · Aug 11, 202132144Ross & Ben pranking Rachel will forever be one of my favourite #Friends moments primarily because Jen’s reactions are real as she didn’t know about the prank 😂 https://t.co/JhhNu4kK7HIn an episode involving Rachel, Ross and his son Ben, Jennifer Aniston wasn't told in advance that Rachel was going to be pranked by Ross and Ben because the producers wanted a more genuine reaction from Aniston. And they got exactly that. The scene involved Ben and Rachel pranking Ross together, but little did she know that Rachel was going to be pranked too. Rachel's reaction to Ross' dummy being thrown down the stairs was absolutely genuine, where she screamed,"Oh my god, David!"This, of course, had to be dubbed.2) Donald Trump wants his blazer blackKhali Ridings@khalinotcharlie“Donald Trump wants his blue blazer black” 🤣🤣🤣 twitter.com/FriendsTV/stat…FRIENDS@FriendsTVTell us your favorite Friends character without telling us your favorite Friends character09:28 AM · Mar 4, 202114672680Tell us your favorite Friends character without telling us your favorite Friends character“Donald Trump wants his blue blazer black” 🤣🤣🤣❤️ twitter.com/FriendsTV/stat…Chandler has always been the one making jokes and passing sarcastic comments. But this one time he himself became a laughing stock for messing up his lines. Matthew Perry delivers the line,"Donald Trump wants his blue blazer black...back!"While it was clear that Chandler mispronounced, the scene was incorporated into the series due to the other character's improvised reactions. It was an actual mistake that Matthew Perry made, and the way everyone made fun of him for the error and his response to it was too funny to not be retained in the sitcom.3) Carol criesHannah Shaw-Williams@HSW3KI'm absolutely stunned and delighted that Friends season 3 got away with a scene where Carol picks a pube out of her teeth after Ross interrupts her anniversary celebrations.Carol and Susan weren't even allowed to kiss at their wedding in season 2.2:30 PM · Apr 25, 202116I'm absolutely stunned and delighted that Friends season 3 got away with a scene where Carol picks a pube out of her teeth after Ross interrupts her anniversary celebrations.Carol and Susan weren't even allowed to kiss at their wedding in season 2. https://t.co/0je8i3Yfx3Early episodes of Friends saw Ross struggling with his first divorce from his then-wife Carol.

However, it could not end that way, leaving viewers in tears. Matthew Perry decided to improvise a bit. In the final scene where the six cast members are leaving Monica's apartment, Rachel suggests that they go have coffee. To this, Chandler replies with his trademark sarcasm,“Sure, where?”The line was a sarcastic improvisation that made for the perfect ending.
