I wrote about them on December 2, 2005.

I wrote about them on November 2, 2006, and again on November 7, 2006.

And again on May 10, 2007.

What do I have to do to get people to pay attention to this impending global threat?  Make an Academy Award-winning documentary?

An aggressive squirrel attacked and injured three people in a German town before a 72-year-old pensioner dispatched the rampaging animal with his crutch.

The squirrel first ran into a house in the southern town of Passau, leapt from behind on a 70-year-old woman, and sank its teeth into her hand, a local police spokesman said Thursday.

With the squirrel still hanging from her hand, the woman ran onto the street in panic, where she managed to shake it off.

The animal then entered a building site and jumped on a construction worker, injuring him on the hand and arm, before he managed to fight it off with a measuring pole.

"After that, the squirrel went into the 72-year-old man’s garden and massively attacked him on the arms, hand and thigh," the spokesman said. "Then he killed it with his crutch."

How long will it be before it is "too late"?
