'Friends'' Greatest TV Twist Came After David Schwimmer Had A Brain Fart And Made A Mistake On Set: 'We're Doing This'

"Friends" remains as one of the most rewatchable TV shows ever even years after it ended, and for good reason. The NBC sitcom has some of the most iconic and memorable moments, whether it’s the fun Thanksgiving episodes, hilarious off-beat Phoebe quotes, or what is perhaps one of the greatest TV twists and the greatest twist on Friends that wasn’t initially meant to be in the script.

A resurfaced interview with writer and producer Greg Malins via Reddit includes him talking about Ross’ wedding to Emily in the Season 4 finale. He shared that the ending of the wedding was something they had “struggled” with to figure out. And at a taping, David Schwimmer was meant to say “I got the cab waiting, Emily,” but it came out as “I got the cab waiting, Rachel” and he apologized. But that brain fart turned out to be brilliant because that’s when the writers knew that that’s what should happen, “We’re doing this.”
