What pseudoscience content makes you laugh?

Personally, I think the biggest pseudoscience is the bastard who touts how organic, pure and natural foods can prolong life and how modern agriculture using fertilizers, pesticides and antibiotics can cope with various major diseases ... In the past, 400 kilograms per mu was a bumper harvest, but now 400 kilograms per mu is an average. Without modern agriculture, hundreds of millions of people would die on the earth.
