About Feng Shui, I remember this show in my country where they invited this expert. Said expert advised the protags to rearrange the few furnitures such that they can't use them, which in turn caused oil (the fossil fuel kind) to spew out from their faucet (off screen).
Then the protags' mom comes in, rages about how the furnitures are arranged and puts them back in place, while one of the protags screams that the oil turned back to water.

Ahh, good times.
