Bert  is Evil !
Document from FBI Alien Dossier

This  photo taken from the Aliens Dossier of the FBI shows the images of the  two most aggressive aliens ever encountered on this planet . The Zeta  Reticuli, allegedly responsible for the cattle  mutilations, the ebola virus, the bubonic plague and the nuclear  age. The Zeta Berticuli, allegedly responsible for infommercials, the deformed frogs of Minnesota and Nonoxynol-9. It is a well supported theory that Bert  may be an alien or a muppet/zeta hybrid.
