Summary[]
After meeting a rich woman named Denise on a blind date, which Larry sets up, Jack brings her home to meet Terri and Janet. The girls soon see that Jack's new girlfriend, Denise, is not as nice as she seems, and she even wants Jack to dress differently and work for her father's cardboard box company instead of following his dream of being a chef. When Denise talks Jack about getting married, the girls panic. Denise even wins over Larry when he tries to break them up at the request of Janet and Terri. Unable to beat around the bush any longer, Janet tries to talk Jack out of marrying Denise, and even grabs his pants. Denise arrives and overhears and misinterprets the conversation, thinking that Jack has a thing going on with his two roommates. This accusation forces Jack to see Denise for what she truly is, and he says a permanent goodbye to her.
