Wednesday on TV: Brooke Shields gets trashy on 'The Middle'

Brooke Shields has, for the most part, played relatively glamorous roles on TV. But she's back as trashy neighbor Rita Glosser in tonight's episode of The Middle (7 p.m., ABC/Ch. 4).

And Rita's collection of loud, large wind chimes puts her at odds with Frankie Heck (Patricia Heaton).

Also on this week's episode, Brick comes up with a new snack idea and Sue tells the family that she and Darrin are dating again.
