But it (the parody) has a lovely section at the end. The idea: get a copy of The Rules, find out for sure if you're dating a Rules Girl, and since The Rules are cultlike in their admonitions to keep following them no matter what, use the fact that you know their strategy already.
I love it.
I also didn't know that "Don't tell your therapist you're using The Rules" was in the official canon. Good to know.
