For a (thankfully) short time we had neighbors across the street we called "The Bumpuses." We lived in a very nice, quiet, comfortably middle class suburb and this "family" kept their black lab-mutt chained to the front porch. The kids would play on the roof when no adults were home and the father, who drove a Chevette without a muffler, would speed through the stop sign every morning.
There was much rejoicing when they couldn't afford the house payment and moved out.
