If you harbor the desire to own a pitbull, I question your intelligence - genuinely. Sorry, but you're a fucking retard and you deserve to have your "pet" go lock jaw and injure your own child or relative. If you disagree, you probably own a big jacked up truck, a gun of some kind and have a barb wire tattoo on your bicep. If you arent a white trash redneck type, you're probably a "wigger." Either way, dont procreate and dont let your dog run around in my neighborhood or there will be words.
Hope this helps.
Update/Edit: Made a logical error in the above. My hypothetical posed the proposition you might live in my neighborhood. That could never be the case because statistically speaking, you have no college degree and make less than $50k a year. We would never live in the same neighborhood. Carry on...
