I can think of lots of pets that I wouldn’t want to own. Things like a big snake, that huge dog from Cujo, and a spider monkey that’s always whacking come to mind. Perhaps the worst pet you could ever own would be a lawyer.
If you feel differently, you can adopt a lawyer just in time for the holidays. The My Pet Lawyer doll thingy is a remote controlled gadget that will blurt out nine different saying like “You talkin’ to me, sharkbait?!” to “Pro Bono? Never heard of him!”
