INSTRUCTIONS: Install fortunes of your devising in permanent or non-permanent media in openable structures, such that passersby will come across them.
Points for actually distributing the cookies with the fortunes. That's the only thing that makes fortunes even better. Not too many points, because I stumbled across the formulation "of your own devising" in the task description, and think that there should be still three more points for whoever achieves to make home-made fortune cookies.
I especially liked the cup one.
