10. You have a reason to kill someone's girlfriend/boyfriend
9. You have something to do when knitting (making a voodoo doll of the girlfriend/boyfriend)
8. Learn something new (evil magic to kill the girlfriend/boyfriend, stalking skills, etc.)
7. When you get in jail for murder you meet new people
6. You a have reason to spend loads of dough (you + cash + star merchadise = CHA-CHING!!)
5. Your star's face eventually becomes your room's wall paper
4. You'll gain plenty of pictures to plaster your school locker with
3. You get the experience of camping outside on the front step of someones house
2. You get to piss off non-teenybopper people, such as Melo's Reality-Facers (hehe!)
