What happens when you give inmates free access to the legal system? You get stupid shit like this:

Embattled NFL quarterback Michael Vick, facing federal charges related to his alleged participation in dogfighting, has been hit with a "$63,000,000,000 billion dollar" lawsuit filed by a South Carolina inmate who alleges the Atlanta Falcons star stole his pit bulls and sold them on eBay to buy "missiles from Iran."

Inmates get bored pretty quickly and commonly file lawsuits as a form of entertainment.
