One possible explanation

Ok, this is strange, sixty heads were found on a Southwest airlines flight. At first it might sound like a shipment from a drug cartel, or a very bad accident. I have a simpler explanation, they were bound for Washington and the U.S. Senate as replacements in case democrats there can't manage to pull their own out of their asses and approve the Keystone XL pipeline. Believe what you want, dingy Harry and his cronies aint got a brain cell between em.
