CELEBRITY WIFE SWAP - 'Bristol & Willow Palin / Joan & Melissa Rivers' - Bristol and Willow Palin reside in Wasilla, Alaska with Bristol's four-year-old son, Tripp, who rules the roost. What Tripp says goes in the Palin household. When Melissa Rivers arrives in Wasilla, she's surprised to see snow on the ground - in May! Meeting Willow and Tripp, Melissa finds it a challenge to deal with Tripp's boyish exuberance, and feels that he needs to have a set daily routine. Aunt Willow is no help when it comes to discipline, and in fact is often the instigator behind Bristol's back. But Melissa is determined to bring structure to the Palin home, so when it's time for the rules change, she immediately initiates a new sticker chart reward system for Tripp. She also applies rules changes to Willow, helping Willow to get one step closer to following her passion in a career.
