Go green or have your private business robocalled and vandalized. It happened to a computer manufacturer in a Greenpeace publicity stunt earlier this week that included William Shatner.

Greenpeace and the Canadian-born actor joined forces against Hewlett-Packard (NYSE:HPQ) and accused the company of "breaking green promises" for not producing products completely free of PVC plastic and brominated flame retardants. Activists from the radical environmental group painted a giant message on the roof of Hewlett-Packard's headquarters in Palo Alto, Calif. that read "Hazardous Products."

And in addition to the rooftop graffiti, Greenpeace set up an automated message to dial HP employee's numbers and then play them a recorded message from Shatner.

For more Saturday night entertainment pleasure, here's the video Neal Boortz talked about this week featuring William Shatner's Denny Crane character ("Boston Legal") "helping" Barack Obama as he defends the Second Amendment:

A practical joke on last night's "Boston Legal" had mad cow disease-afflicted lawyer Denny Crane (played by William Shatner) believing the RNC wanted him as the presidential nominee. 

And it left "Boston Legal" writers with plenty of opportunities to slam Republicans, like this exchange that suggests former Republican President Ronald Reagan had mad cow disease instead of Alzheimer's:

ALAN SHORE: Do they know you have mad cow?

DENNY CRANE: They're looking for the next Ronald Reagan, and he had it at the very end.
