Dowsing?

[Tiberius]

Dowsing isn't real.

How many times have you tried it!

A few actually. It works great if you already know where something is, or can't prove the result. When I was a kid we had a family friend come over and do some dowsing. He said he was able to redirect some underground streams beneath our house. An amazing feat if you ignore the fact that there's no way anyone could verify what he said.
