Years ago when I was learning about Paganism in a group setting, a bunch of us went out to dinner after one of the meetings. One of our leaders/instructors and I were the first ones at the restaurant and we needed to get a table for 15 or so people. It was fairly crowded and the instructor said to me, "Well, we're Witches maybe we can do a spell to make a bunch of chairs." Without missing a beat and without realizing I was going to say it until I was saying it, I replied, "I'm just a new Witch - all I can do is produce a little stool."
The instructor had a funny look on her face the rest of the night.
