The night before the wedding, Ellen and Audrey throw a bachelorette slumber party for a despondent Paige. They invite over a male stripper, a psychic, and Paige's neurotic, high-powered, boss Lorna Irons. But Ellen's plan backfires when the ladies accidentally get two strippers for the price of one. In addition the psychic Madam Debbie Johnson's predictions for Paige come true in unexpected and unusual ways, which leads the ladies to force to move their party from Ellen's apartment into her unhinged parents house. Meanwhile, Spence and Joe try to have a good time at Matt's bachelor party. It's at a local strip club where Spence tries talking himself out chugging beer by explaining to the crowd about the pros and cons of marriage.
