Episode "Hank and the Great Glass Elevator" features the only appearance of Bill's ex-wife, Lenore.
Ann Richards actually played herself in S5:E11 "Hank and the Great Glass Elevator." Ms. Richards served as Governor of Texas from 1991 to 1995, and she was only the second female to do so. She gained national attention when she delivered the keynote address at the 1988 Democratic National Convention; she was Texas State Treasurer at the time.
