Phoebe suggests that Monica sings at Mike's piano bar. After some doubt, Monica does. The patrons love her - but not because of her singing, really because they can see through her shirt, with no bra underneath. Meanwhile, Ross meets a woman at Central Perk and discovers after he brings her to his apartment that she likes to look at Ross's things. Rachel, thinking it's not right anymore, decides to move back in with Joey, taking Emma with her.
