The One Where Monica Sings

S9 E13: While Rachel sorts out her conflicted feelings for her handsome co-worker Gavin (recurring guest star Dermot Mulroney), Ross recruits Chandler to help him meet attractive women in order to make Rachel jealous. Meanwhile, Phoebe regrets bringing Monica to karaoke night when Monica takes the microphone and delights in the applause--unaware that the guys in the audience are cheering because they can see through her dress. And Joey submits to painful eyebrow waxing before a photography session. Recurring guest star Melissa George appears as Molly.
