On "Friends", what's Joey's usual pick-up line?

On “Friends,” Joey’s usual pick-up line is “How you doin’?”

Joey Tribbiani, played by Matt LeBlanc, delivers the phrase with a slow, flirtatious tone and a knowing expression. Although the words sound like an ordinary greeting, Joey uses them as a confident opening line when he meets women he finds attractive. The humor comes from his absolute faith that the line will work.

The catchphrase became one of the defining running jokes of “Friends,” especially because Joey’s friends understand how predictable it is. Rachel, Monica, Phoebe, and Chandler occasionally hear him use it, while Joey is often surprised when it fails. The line also became closely associated with Joey’s image as a charming but not especially sophisticated womanizer.

A common mix-up is treating “How you doin’?” as merely Joey’s general catchphrase. It is certainly used as a greeting in some scenes, but the trivia question is specifically asking about its best-known role: Joey’s signature pick-up line. The phrase was popularized by “Friends,” even though similar wording existed in everyday speech before the show.
