If all you have is a hammer, everything looks like a nail. After snagging his toe, Mr Nogginbody visits his local hardware shop in search of solutions. Armed with a shiny new hammer, he successfully fixes the nail protruding from his floor. But the satisfaction of his first repair carries him away and he figures that anything resembling a nail-from a lamp switch to a fire hydrant-can be fixed with a good whack. The results are predictably and theatrically disastrous until Mr Nogginbody arrives at a gentle awakening and recognises that not everything is a nail.
