A concrete buffer is a handy tool to have at a worksite, as it levels out the concrete to ensure a smooth and level surface once it dries. Unfortunately, the buffer on this construction was possessed by the soul of James Brown, because it went out of control and performed its own dance around the site. The guys, at least, got free lunch out of it. This job pales in comparison to Boston's "Big Dig," a project with an initial completion date of 1998 and cost of $2.8 billion. It involved the erection of several tunnels, roads, and bridges to relieve the city of perpetual gridlock. Of course, it didn't go according to plans, by not being complete until 2007 and at a final cost (with interest to be paid by 2039) of $14.8 billion.
