One of Monica's former best friends. Their friendship fell apart when she asked him to be her boyfriend, and he refused because she was fat. She uses this story in juxtaposition to Chandler's camp girlfriend, who he dumped because she was fat. Monica is still very hurt from his actions and tells Chandler that if he came to apologize to her now, despite it being many years later, she would appreciate it.
