It makes perfect sense that she was a wannabee standup comedian, as the skill sets are exactly the same:
- Deliver a scripted performance without breaking character or showing any insecurity, no matter how badly you are bombing.
- Start with some normal human emotion or experience and turn it into something completely absurd or horrifying.
- Ignore or shut down all hecklers, especially those people who are wittier than you.
- Have absolutely no respect or sensitivity for basic human decency, including rules of etiquette, religion, race, sexuality, gender, physical handicaps, family bereavement, etc., in the ruthless pursuit of scoring with the audience.
