Cookie Tribbiani
Cookie Tribbiani is one of Joey's seven sisters and is the one who punches Chandler after he fails to recognize which sister he kissed at the party. 'Cookie' may just be a nickname. She makes her sole appearance in "The One Where Chandler Can't Remember Which Sister".
She remarks to Phoebe that she shot her husband at some point in the past, although this could have just been to freak Phoebe out.
Cookie was portrayed by Alex Meneses.
