The Tin Foil Hat Society is a group which aims to protect its members from the nefarious organizations which currently operate across the globe, while providing a means to safely contact one another. Numbers are never revealed as to how many members are part of the THS, but the group is often described as "Large in number".
As its name suggests, all members of the Tin Foil Hat Society have tin foil hats which they wear at all times. Furthermore, members may have tinfoil ties, glasses, radars, etc.
Their contact alludes to the fact that they employed Jack Cannon as an agent of the Tinfoil Hat Society. Additionally, it is said that John Green is a contact for the society. A commander in the societies name is "OptimumGolem3", but no other information is given. It is mentioned in the Secret Agent that Deep One Dave is an agent. In the same video, it is revealed that top secret agent Yuri Puuki has gone MIA (Missing in Action).
