[2] She was a natural performer throughout her childhood and into high school as she was known to improvise bits with friends and play the role of the mascot on her cheerleading team.
[3] After high school, Weinstock went to Emerson College but dropped out to move to New York and try acting and dance, succeeding in acquiring a few Off-Broadway roles.
Around 1963 she became a hostess at the oldest rock and roll club in NYC, Greenwich Village's the Bitter End.
[5] Weinstock also wrote the play, "Molly and Maze" that she put on with her daughter, Lili Haydn a few times.
On one occasion, Weinstock was too sick to get dressed for a show but still wanted to perform, so she wore a bathrobe on stage.
"[6] However, she preferred live performance as she found the time constraints of her television appearances constricting.
[10][14] She joked about her marriage and dating and was also aware of the difference between how women comedians could act versus men.
[16] Through this venue, Weinstock participated in the USC College of Continuing Education Workshop, "Women and Comedy" in March 1985.
Her close comedic friends in the 1980s included Larry Miller, Lucy Webb, Sandra Bernhard, Diane Nichols, Robert Weide, Jay Leno, Jerry Seinfeld, Paul Reiser, Kevin Pollak, Sam Kinison, Paul Mooney, Richard Pryor, Robin Williams, Hennen Chambers, Carrie Snow, Joanne Dearing, Ron Zimmerman, Bill Maher, Argus Hamilton, Taylor Negron, and Phyllis Diller.
Towards the end of Weinstock's career, Joan Rivers accepted the invitation to write the foreword to her book, "The Lotus Position," but changed her mind shortly after.
Before Haydn left to attend Brown University, she and Weinstock performed a show together called "Molly and Maze" at the Eagle Theatre in Beverly Hills; they reprised the show in San Diego at the Gaslamp Quarter Theatre Company's Hahn Cosmopolitan after Haydn graduated.
The night before she and Haydn were to go to a clinic in La Jolla that specialized in alternative medicine, she had a seizure that resulted in a herniated brainstem.
Weinstock was written up in the book of Great Jewish Mothers by Paula Ethel Wolfson.
