Approached at Whole Foods on Sunday by a very personable woman handing out homeopathic samples for leg pain, my friend Deborah Warcken asked the woman if she knew how homeopathy worked? When the woman answered in the negative, Deborah handed the woman this card. I received these from Jay Diamond at SkeptiCal and had just given one to Deborah 30 minutes earlier, at a skeptics meetup.
