This is my theory, (slightly altered from John Thomas)
A few years ago in the Kubota manufacturing plant, there was this cute secretary that had been given the job of making the maintenance schedules for the Kubota BX line.
She was cutting and pasting columns in her charts when the boss interrupted her to get him some more coffee pronto ! She went around the corner to the lunchroom to get some more, only to find that coffee pot empty and burning on the element so much so that just then it popped the fuse and the office lights went out. So she figured she would go downstairs and get some coffee from the Kubota assembly line lunchroom. She was walking past the front wheel line when her skirt distracted the machinist who was setting the tolerances for machining the next batch of front rims. Unfortunately the machinist did not double check his tolerances and the next batch of 500 rims was made and later added to the partial pallets of good rims in the warehouse.
The secretary managed to get that coffee and got back to the office to find that when the fuse blew, her computer went off too, without saving, and she never did get around to fixing that spreadsheet of maintenance schedules.
So we can blame:
1. the boss for not getting his own coffee
2. the machinist for stealing coffee from upstairs and being a leg man
3. the electrician for putting the computer on same circuit as coffee pot
4. the computer dept because they didnt install auto backup in her computer
either way it is a mans fault probably
