Rudy and her girlfriends are eager not only to be older, but to see the hot rapper "J.T. Freeze" perform. To do so, they lie to their parents to sneak into an underage club called the "Exchange Club" (whose minimum age of 16 is still too old for them). However, Lance reveals how junior high schoolers sneak into the Exchange when asked by Mr. and Mrs. Huxtable about the club, leading Lance, Charmaine and Pam having to sneak in to supervise. When a ticket draw leads Pam to winning a dance with J.T. Freeze, everyone's cover is blown. Ultimately, the Huxtables "understand" how Rudy and her friends wish to spend time with older people, punishing them by forced volunteering at a retirement home once the fun is over.
