As I write personal statements for graduate school, I want to highlight my hard work through humor and also just show my personality. As someone who works full time (in order to fund my education) as a carpenter and does research/studies in their free time while working towards a masters degree, I had made a joke in one of my personal statements that goes something like this.
As a full-time masters student, I've had to support myself as a student, requiring me to seek a full-time job in addition to going to school at night and spending my free time doing research and studying. I'm kind of like Matt Damon from Good Will Hunting but just better-looking and much smarter.
The final statement will have the joke stated more elegantly but that's the general idea. Although I am being sarcastic, I realize that this might not be evident for everyone that is reading it or might come off as arrogant or trying too hard. Additionally, I'm afraid that the joke might be inappropriate.
What is the general consensus on humor in a personal statement. Additionally, any comments on my specific joke are appreciated. (This question specifically pertains to personal statements, not statements of purpose or statements of intent.)
This school has a separate writing sample for statement of purpose and asks that the personal statement satisfies the following "We are interested in learning more about you as a person and how your background and experiences motivate you to make positive contributions to your community. There are no requirements for what to include;"
