How to stand out from the rest of the admissions pool

Does being "President of the Lady Gaga Fan Club" belong on your college resume? High school students are encouraged to join clubs, take on leadership roles, be involved in community service - not just because these are wonderful opportunities for growth, but because they "look good" on the college resume. But where to draw to draw the line between a real experience and a whimsical hobby? If it is something the student is genuinely committed to, has been involved with over a period of time, has helped them to gain worthwhile skills, and reveals something appealing about the person, it should probably go on the resume. In this way, a resume can be used to help the college applicant stand out from the crowd.
