According to BoingBoing TSA is following up on it's recent decision to ban gels, and liquids and is addressing a larger more deadly threat--carry-on snakes.
The order includes a list of snakes banned: vipers, asps, garden, pythons. However the agency remains silent about whether the snakes have to be "motherfucking" or whether this applies to any snake.
It's unclear whether Solid Snake from Metalgear Solid is banned. He's neither a gel, nor a liquid. So I'd figure he might be allowed as carry on. However, Jake "The Snake" Plummer is most certainly banned, for the all to real fear that he'd readily turnover the plane to terrorists.
