Concrete buffer snaps, goes loco, terrorizes its former masters

It's the narration of two gentlemen (Spencer Laboda and his father) who record and comment upon this incident in which a crew of construction workers improvise a series of tactics (some very unwise ones included!) to recapture, a spinning, potentially lethal concrete polisher on a jobsite that really makes this work. Laboda notes, "nobody was injured... we bought lunch for some of the participants. This was a great construction crew and they built a magnificent facility for us to enjoy every day."
