How can you tell this video is from the early 1990s? If the hairstyle doesn’t give it away, then the step-by-step instructions on how to turn on a computer and click a mouse ought to offer some major clues. It’s hard to remember a time when anyone needed a DOS tutorial, but it was only about 20 years ago.

“It looks like a TV, but it’s not a TV,” tutor Kim Komando explains in the segment entitled “Komputer Kindergarten” while highlighting the monitor. And those old floppy disks? They go in a computer “just like video tapes go into a VCR.”

Seriously? Who the hell ever thought that? Apparently a lot of people. And if that sounds computer stupid, get this: Ms. Komando actually explains that hitting the wrong button won’t make the computer blow up. Damn. Is this remedial computers 101 for dumbasses? Actually, yes. The tutorial is the first in a series of educational training tapes called Komputer Tutor.

Not only does Komando’s hairstyle date the tutorial, but her reference to programs gives it away. She describes the “most current version of DOS, DOS 6.0,” which was released in 1993. Sounds about right after checking out her hair.

It’s still unbelievable anyone actually had to explain that since she made a mistake, she can just use the backspace key, and, even better, “press any key means press any key on the keyboard.” No shit, Sherlock.

Komando’s detailed explanation of the mouse, where she describes the proper place to put your fingers, as well as the meaning of pointing, clicking and dragging, is almost too much. But there were a lot of idgits out there for a long time who were pretty clueless about the simple device.

Got time for a quick anecdote? About 12 years ago—we’re talking circa 2001 here—a customer called in to a company I used to work for to get help with the Web site. After a lengthy explanation of what icon to click on and no success pulling up the page, it turned out she was taking her mouse and physically tapping the icon on the computer display. Seriously. She could definitely have used Ms. Komando’s tutorial. So believe it or not, these people are out there, probably still to this day.

But for this rest of us, this video amounts to some funny shit.
