the best TV shows of all time, and among them is Friends. Created by David Crane and Marta Kauffman, Friends premiered on NBC in 1994 and ran for a total of 10 successful seasons, ending in 2004.

Friends’ premise was simple, as it focused on the lives of a group of six friends, doing their best to navigate adulthood in New York City, but it proved to be quite successful. Friends seized the comedic chops of every one of its actors, but its main cast was especially good at improvising. As a result, Friends is packed with funny and memorable moments, but some of those scenes were actually completely improvised by the cast, and were so good and natural that they made it to the final cut.

It turns out that Thomas knows his wife is cheating on him and thinks it’s with her gynecologist, but in reality, it’s Tim who has been sleeping with his wife.

1 Chandler’s Final Line In Friends

Rachel suggests they get coffee before they leave, and they all agree. However, Chandler casually asks where they’re going after spending years going to Central Perk every day.
