The signals from the tinfoil on their heads are making it hard for them to concentrate?
It is a well known fact among the initiated that the most technologically advanced forms of tin foil hats are SOOOOO powerful there IS the possibility that they magnify the wearers inner thought patterns to such a DISTRACTING degree that the assimilation of outside stimulus is impossible.
Therefore, all wearers of the most advanced tin foil head gear are strongly advised to stick bits of chocolate into the nooks and crannies of their hat. The cocoa butter in the chocolate has the effect of filtering out the noise of the screaming voices in the wearers' heads.
TIP: The scent of the chocolate also enables the wearer to disguise him/herself as an unobtrusive sweet in a candy dish.
Yes and for all their impressive psychic powers..they can see things none of the rest of us can see....and yet they can't seem to comprehend facts that are right in front of their face.
