Knut

Knut (short for the German word Knutenadorschnitzenmachinatassen, meaning "precocious killing machine") is a polar bear cub living in that most deviant of brothels called the Berlin Zoo.

He has outraged Stephen Colbert by forcing him to agree with Frank Albrecht, one of those wackjob animal rights activists and spiritual descendant of Adolf Hitler, albeit in their shared aversion to his very existence.

Threat Down appearances
Knut is such a dangerous threat that he is the subject of the first and only Mini Threat Down at number .5. After posing together at a Vanity Fair shoot, he and Leonardo DiCaprio are engaging in a disturbing Man-Bear love affair.

On May 8, 2007, Knut was declared Threat Number One.

Death threats
On April 19, 2007, Knut was the subject of a series of death threats. Clearly these were not the works of the Colbert Nation because


 * 1) they'd know that bears can't read threat letters, and
 * 2) they would have had the giant brass balls to go through with it.

Other theories concerning Knut's existence
It is highly likely that Knut is a component weapon in the resurrected Nazi war machine.
