S01E05 - "Maude and the Radical"

Maude organizes a fund-raising party for a black militant politician and invites all her rich white friends under false pretenses. Maude also tries to get black people to attend the party, but the best she can do is make Florida go to the event, calling her Florida DuBonnet. Then, during the party, Maude mixes Arthur's prescribed tranquilizers with alcohol, which causes her to reveal the fundraising part of the party, and causing her guests to leave.
