From hints in the show, Mary formerly drank a lot and often used her femininity to get what she wanted from men. From references and one episode about her parents, it appears that her father had affairs and her mother drank a lot. Mary comes from a dysfunctional, trashy family, but she and sister Renata have become successfulRenata is rich, while Mary is a professor and doctor. In one episode, Dick marries Renata, in order to divorce her and get her to promise she will not build a library at Pendelton that will cast a shadow in Mary's office. Renata was played by guest star
Megan Mullally (best known for playing
Karen Walker on
Will & Grace). Mary also has a younger brother, Roy Albright (
Bronson Pinchot), who claims to have been abducted by aliens. This completely freaks out the family; to this end Sally and Harry take Roy out a cornfield to "killroy" as the plan is called. In the end, he is found out to be lying. Mary's siblings, Roy and Renata, only appear in a single episode each and are never seen or referred to outside of these episodes. Even in family anecdotes, Mary does not mention her siblings. When Mary was a child, she was overweight and unhappy. She and her parents used to vacation at a bed and breakfast every summer when she was a child, and her parents wreaked havoc with their partying and drinking. As seen in "The Dicks They Are A'Changin'", Mary was a part of the
1960s counterculture in her youth (
flashbacks showed her dressed in
hippie garb), though she mentions she "never made it to
Woodstock". Mary attended
UC Berkeley in the late '60s and was apparently involved in the
Free Speech Movement there. At one point during her youth, she worked at a
Dairy Queen. ==Alternate universe==
