My favorite 'how not to' example is a dustpan, made with strengthening
ridges on the bottom sides of the pan, in such a way that its impossible
to put the front edge of the pan flat on the floor to pick up the
sweepings - they go underneath the raised edge on the front lip created
by the ridges. *Obviously the designer ( and any subsequent reviewers )
never used a pan.


*MY* favorite (actually, most hated...) "how not to" is the spare tire
carrier on domestic (Ford, GMC, etc.) full-size trucks. My folks had
a car repair and tire place. I've cursed out loud in front of my
mother while trying to remove/replace a tire under a truck. A
(slightly) better design is the chain hoist system used on some
smaller imports. I hope there's a special place in hell for the
Mercedes-driving engineer that designed this thing (you know HE never
changed a flat in his life!).
