Imagine you are a high-school principal charged with keeping your students away from illegal drugs, at least during school hours. Trained dogs might be accurate, but they are too expensive. It takes too long to go through every single locker. What can you do? Buy a $900 dollar dowsing rod designed to find drugs! Pot heads, your days are numbered.

The talk is by Skeptic Society founder Michael Shermer. Perhaps skeptics are just a source of resistance to new ideas, obsessed with ridding their lives from false positives. But I'll take $1 worth of skepticism over a $900 dowsing rod any day.
