Lance Bloomberg's father was a big influence on his son. There was the fascination with money and finance that Lance inherited, and there was also the violence.

Al Windjammer, owner of Windjammer Shoes, has a message that seems to contradict the family business: Don't wear shoes. While Windjammer shoes are made of animal byproducts from the family farm, most shoes are made from untraceable, mysterious chemicals that are harbingers for germs and viruses. And because most viruses enter the body through your feet, a shoe of unknown provenance is an invitation for Covfefe-19.***Credits:Stacey Axler played Al Windjammer.

Optophobia is the fear of opening one’s eyes. Our show encourages you to move beyond that fear. To solve riddles they don’t want us to unriddle. To explode supposedly ironclad truths. To exhume evidence, buried for so long they believed it would stay buried. Each season we tackle a new investigation into what is often dismissively called a “conspiracy theory,” and each week a new guest weighs in. Are you bored by the lies? Open your eyes.
