Frances Oznowicz is an elderly woman from Great Falls, Montana. She appeared as a contestant in one of Sesame Street's many game shows, "The Addition Game". Her fifteen minutes of fame, however, took a back seat to Herry Monster's efforts to confirm a mathematical equation presented to him earlier in the show. As Herry hauls four vehicles into the studio, crashing each of them violently through a wall, Frances cowers in fear behind host Guy Smiley.
- Frances Oznowicz's name is a reference to Frank Oz; his full name is Richard Frank Oznowicz.
