While we're all thankful Chandler ended up with Monica, we can agree that some of the show's memorable scenes included his obnoxious ex-girlfriend, Janice.
What to wear: For Janice, a black dress and curled hair (or curly brown wig), and her signature, nasally "Oh. My. God." line. For Chandler, a button-down, dress pants, and a "please help me" look.
