insanity

how can you tell when someone has lost their mind? how can you tell if someone is crazy? when they think thoughts that are completely out there? when they think someone that can never be a possibility can be a possibility? is someone crazy when they believe in aliens? or god? or other completely unbelievable things? is there an way to test people, without sending someone to a psychiatrist, to see if they are crazy? what we need is amicrazy.com or aretheycrazy.com. you go there, enter the particulars, then have the site determine your level, or someone else level of insanity. at least it would be a good pre-screening method prior to sending out the guys in white coats and butterfly nets.
