While the show was conceived as a comedy, scripts also incorporated much darker humor, drama and controversy. Maude took Miltown, a mild tranquilizer, and also Valium; she and her husband Walter began drinking in the evening. Maude had an abortion in November 1972, two months before the "Roe v. Wade" decision made abortion legal throughout the U.S., and the episodes that dealt with the situation are probably the series' most famous and most controversial. Maude, at age 47, was dismayed to find herself unexpectedly pregnant. Her daughter Carol brought to her attention that abortion had become legal in the state of New York. After some soul-searching (and discussions with Walter, who agreed that raising a baby at their stage of life was not what they wanted to do), Maude decided at the end of the two-part episode that abortion was probably the best choice for their lives and their marriage. Noticing the controversy around the storyline, CBS decided to rerun the episodes in August 1973, and members of the country's clergy reacted strongly to the decision. Thirty-nine stations pre-empted the episode. The two-part episode was written by Susan Harris, who would work with Bea Arthur again later on "The Golden Girls".
