It worked for Phoebe

I'm not a Halloween fan, anymore, and haven't done a costume in 6 years. I was an Uber Driver so dressed up once. What a stupid job that was but it kept me afloat. The outfit was a zombie Groucho Marx with a floppy rubber duck. Nobody got it.

Except that witchcraft doesn't work any better than other superstitions and religions. I was dating a self-professed witch. Once we were stopped at a light and she sought to use her power to change the red light. Even after three tries, it stayed red. That's just an anecdote, of course, but if any religion worked, it'd be obvious.
