why are all the friends last names arquette
The One After Vegas Between seasons, Cox married David Arquette, becoming Courteney Cox Arquette. An in-joke reference to this is made in the opening credits, where the rest of the cast have "Arquette" appended to their names. The dedication "For Courteney and David, who did get married" appears during the fade out to the tag scene.[1]
Chandler Bing Chandler's best friend is Ross Geller (David Schwimmer), who was his college roommate. He and Ross were in a band named Way/No Way during college. He met Ross's sister, Monica Geller (Courteney Cox), and her friend, Rachel Green (Jennifer Aniston), while celebrating Thanksgiving at Ross's House. Chandler was the first person to know about Ross's love for Rachel. He moved to New York City and lives across the hall from Monica and, through her, meets Phoebe Buffay (Lisa Kudrow). At some point during this time, Joey Tribbiani (Matt LeBlanc) moves in with him and they become best friends. Chandler has a very good sense of humor, and is notoriously sarcastic. He is the highest earning member of his friends circle on account of responsible income management, having learned the value of money from a young age. He suffers from commitment issues, but later marries Monica.
