The competitors get the surprise of their lives when they find out that three original cast members of the legendary 70s sitcom will be tasting their food! Christopher Knight, Maureen McCormick and Susan Olsen -- famous for playing siblings Peter, Marcia and Cindy Brady -- take on the role of Chopped judges. In all three rounds, the baskets feature ingredients inspired by the groovy show, including pork chops and applesauce.

The chefs take on a melted cheese theme with the hope of giving the judges stretchable, craveworthy dishes. A platter of comfort food yumminess is at the center of a decadent first basket, and the ultimate melty cheese dish -- fondue -- finds its way into the second basket. In the dessert round, the remaining chefs have to get creative with the strange, colorful cheese snacks in the basket.
