Argentina court rules that goldfish have rights

When you go to a sushi bar, one of the things you don't usually see on the menu is goldfish. I mean, we typically don't eat goldfish unless it's in cracker form.

And we're not talking about just the right to not be eaten, but actual rights afforded to -- as the country calls it -- sentient beings.  Greg shares his legal insights into this bizarre story.
