Start a discussion group on myspace or somewhere like that, and post the kookiest doctrinal teachings you can find (ie birds picking the eyes out of unbelievers), making it look as though you agree with the teachings. Then you can both get your hours in and ensure no one is inadvertently impressed with what you say.
Or as others said, put some anti-cult stuff in the magazines as you place them. A handwritten note: "Help! I am trapped in a mind control cult." I have some brochures if you want them!
OR better yet, count your time on JWD!
