Autism rule
(slrpnk.net)
Be sure to follow the rule before you head out.
Rule: You must post before you leave.
Rule no. 1: People are stupid. A person will believe a lie because they want it to be true, or they fear it might be true. A person's head if full of information, most of it is wrong. People are also convinced that they are perfectly able to determine truth from lies, which makes them all the easier to fool.
Bonus points if you get the reference without googling it.
