Defusing a bomb, repossessing an airplane, taking over the world… very few people need detailed instructions on topics like these. But Ari Cagan, self-taught ambassador of useless information, is contractually obligated to explain them to you anyway.  "Things You Don't Need to Know" is a new podcast hosted by Ari Cagan from HyperObject Industries and Three Uncanny Four Productions. New episodes starting February 18th.
