Margaret Cho famously has impersonated her mother in her stand-up routines.

In this outtake from the new PBS documentary, American Masters: The Women’s List, premiering nationwide 9 p.m. Friday, Cho describes why it has been important to voice her mother accurately, as well as how her Korean father had no such accent, and how both of her parents accepted Margaret’s bisexuality as well as her comedy.

Cho is one of 15 women featured in Timothy Greenfield-Sanders documentary for PBS; the others: Madeleine Albright, Gloria Allred, Laurie Anderson, Sara Blakely, Edie Falco, Elizabeth Holmes, Betsey Johnson, Alicia Keys, Aimee Mullins, Nancy Pelosi, Rosie Perez, Shonda Rhimes, Wendy Williams and Nia Wordlaw.

This weekend, Cho also premieres her latest stand-up special, psyCHO, also 9 p.m. Friday, but on Showtime. And here’s the trailer for that!
