Reply #58: I found the "Zebra" reference, but not the "oreo" one:

From Wikipedia:

During the January 11, 1975 episode of All in the Family, Edith Bunker gave a tearful good-bye to her neighbor, Louise Jefferson, as she and her husband, George Jefferson, and their son, Lionel, moved from a working class section of Queens into a luxury apartment in Manhattan, thus launching a spin-off of All in the Family and creating the 11-year run of The Jeffersons. George had long ago begun his career as a dry-cleaner and now was operating seven stores in ghetto sections of New York City. Louise made friends with Tom and Helen Willis, an interracial couple, who George insultingly called "zebras". Tom and Helen Willis had two children: Allan Willis, their overzealous college drop-out who abandoned the family, passed as a full-blood Caucasian and lived in Paris for two years, and Jenny, their beloved, hard-working, fashion designing, daughter, who dated Lionel. Jenny and Lionel were married on Christmas Eve, 1976, but then divorced in the winter of 1985, due to marriage problems and disagreements regarding their daughter, Jessica (Ebonie Smith).
