Those "grease nipples" were invented by a fellow named Zerk back in the teens? 1920s? - anyway, you come up with a mundane but hugely needful invention & you can put your name on it, & then in another 80 years or so people will be asking "Whutz a Nogbad? I call'em magnetohydrodynamic adjustable spanners" & getting derided for it by the clueful old geezers...
