Terrifying idea that just came up in conversation after dinner: left-handed CDs. I decided it was a spec pushed by the Soviet Union in order to be assholes, like that horrible 'metric inch' system.
Totally OT (sorta) but I've heard it claimed that machining in metric is a PITA. If one was getting modern lathes, mills, etc, would one want them to be natively metric or english units?
Slightly less OT, we us decimal feet for most civil engineering stuff (in the barbaric USA). While the architects use inches. So, their CAD drawings are actually 12x the size of ours. Sigh. When architects do use metric, it's in mm, IIRC.
