"We've been told that Barry Bonds once received an injection of presumably a performance-enhancer in his belly button.

We've been told that Bonds threatened to chop off the head of his former girlfriend and slice out her breast implants "because he paid for them."

We've been told that Bonds' testicles shrunk.

What, though, have we really learned in the perjury trial of baseball's all-time most prolific home run hitter?

Plenty. But none of it has been about Barry Bonds. Instead, the most interesting development is what we've learned about ourselves.

We've learned how disposable celebrity is in America. We've learned how quickly we're willing to turn and move on.

We've learned how hollow sports greatness can be. We've learned how convinced we are of Bonds' guilt.

More than anything, we've learned how little people care about sports stars violating their bodies with needles and drugs for the sake of our entertainment.
