Steve badgers Brandon into pledging the Kappa Epsilon Gamma fraternity. The frat brothers disapprove of Brandon's involvement with Josh and the Progressives. Brandon disassociates himself from the party when it proposes the elimination of all fraternities and sororities. He disappoints Steve by not joining the KEG house, but is made an honorary member. Kelly, Donna, Brenda and Andrea pledge the Alpha Omega sorority. Kelly runs into John Sears, a guy who spread rumors about her after they dated in high school. He insists that he has changed, and Kelly stays out late talking with him after a party (which Dylan refused to attend). Dan Rubin, Andrea's resident advisor, warns her of possible discrimination. Andrea wears a necklace of the Star of David to a ceremony, and the sorority president chastises her for "making an issue" of being Jewish. Leslie later explains that she is Jewish, but not very religious; she apologizes for projecting her personal issues onto the house. Only Kelly and Donna elect to join a sorority. Donna livens up the late night radio show when she compares David to a dog. Music: 'Disco Inferno' by the Trammps, 'Get Down Tonight' by KC and the Sunshine Band, 'Boogie Oogie Oogie' by A Taste of Honey.
