Katherine Heigl Stars in Anti-Balls PSA

Katherine Heigl hates balls.

The actress makes this very clear in a new public service announcement on the Funny or Die website.

She reveals in the video that the real motivation behind her animal advocacy isn't her love of animals, but purely her hatred for balls.

Katherine goes on to clarify that this isn't some pun on tennis balls or yoga balls, but "terrible, terrible testicles."

"Unfortunately, I can't cut the nuts off human men...yet," Katherine explains while strolling in front of cartoon anti-ball posters. "So I've dedicated my time to the neuturing of dogs cause that's legal!"

While the video is clearly a joke, Katherine's messasge is very serious.

The website mentioned in the video, IHateBalls.com is a real website for the Jason Debus Heigl Foundation's campaign to stop the killing of animals in shelters and promote the spaying/neuturing of pets.
