Mary Katherine Gallagher

Mary Katherine Gallagher is a fictional character invented and portrayed by ''Saturday Night Live'' cast member Molly Shannon from 1995 to 2001. She was considered the first breakout character from the new 1995 cast and a significant marker of the increased influence of women writers on the show in the 1990s. Shannon portrayed the character in a 1999 film, ''Superstar'', and she also reprised the role when she hosted ''Saturday Night Live'' in 2007. Shannon first created an early version of the character when she was in school at NYU, during a comedy show directed by Madeleine Olnek. Provided by Wikipedia
