Reagan Yun is a gorgeous nerd who would rather solve a puzzle than dance all night in a club. “I like doing crossword puzzles, since they make me feel smart,” says the finance and banking major. “I'm a great piano player. I was always asked to play for my high school choir and my church choir. My favorite things to play are ragtime and classical music.” When Reagan isn’t enjoying herself at home, the brunette from the University of Missouri works as part-time waitress at a comedy club near her school. “I like guys who have a good sense of humor,” admits our voluptuous Coed of the Month for December 2006. “I want a guy who can be fun and doesn't take himself too seriously.” Now that she’s a Playboy model, we doubt she’ll have a hard time finding her dream man.
