Proving David Hannum right on the sucker born every minute front, check out this website for Bravina, a self-described “special blend of nine natural supplements” that “will help prepare you to execute an articulate public presentation.”  For a mere $19.95, you too can have six tablet-sized amalgams of passiflora, motherwort, St. John’s wort, ashwagandha, Valerian root, Eleuthero root, panax, ginkgo biloba, and octacosanol — and the tantalizing prospect that in popping these pills you’ll find “the control and cognition you need to execute an articulate and effective public speech.”

Caveat Emptor.
