Tin Foil Hat Brigade 

A person who wears a tin foil hat that is made from one or more sheets of aluminium foil, or a piece of conventional headgear lined with foil, often worn in the belief or hope that it shields the brain from threats such as electromagnetic fields, mind control, and aliens.

Johnny thinks aliens helped build the pyramids, guess he's a member of the tin foil hat brigade.

tinfoilhattery 

Mocking term for debunked conspiracy theories. Often used in reference to 9/11 theories and people that treat the DaVinci Code as non-fiction (tinfoilhatters, if you must)

After reviewing these facts, maybe it can be seen that "loose change" etc. etc. is so much glorified tinfoilhattery
