Do you live in a rough neighborhood? Instead of getting a dog for you backyard have a look at this Paintball Sentry Gun.

Sure, I have no reason to own one of these, but I want one none the less. Having a bad day, set it up on the front porch and order a pizza… delivered. I’d likely get arrested, and I doubt I’d ever get pizza delivered again, but you have to admit it would be funny. Nice solution to that annoying neighbor’s dog too.
