Crest Smile Throwdown: Here's What Really Happens When You Talk To Strangers (Ep. 3)

There's a certain type of person who says anything to anyone, and that's the person you avoid. But, we're all about defying the norm, so we got two R29ers to sing and dance and, yes, talk to complete strangers in the latest edition of Smile Showdown.
