Molly Shannon as Mary Katherine Gallagher

Memorable Quote: "Sometimes when I get nervous, I stick my hands under my arms, and then I smell my fingers."

An uncontrollable geek who only dreams of stardom, Molly's Mary Katherine Gallagher is cringe-worthy. She smells her armpits, delivers monologues from bad made-for-TV movies and falls and breaks everything in sight.

The reason why this character is so remembered, and loved, is because Molly Shannon was one of the first ladies to do full-on physical comedy. She could tear down a set by throwing herself at it, without blinking an eye.
