BoingBoing readder Cristóbal Palmer responds to a recent BB post about Tactical Usage of the phrase "Oh Snap!", and says:

My own flowchart. Starts with the question, "Is it fucked up?" and goes from there. Did this a long time ago. Original version I did here, blog post I just posted with more legible, updated version here.

Reader comment: Michael says,

I saw a variation of this diagram on the door of the men's room in the Texas Chili Parlor in Austin a few years back.

That flowchart you posted seems to be heavily inspired by this one from the book Antarctica by Kim Stanley Robinson, published in 1997.

I couldn't find a copy online, but I have a scan of it that I attached.

Mark says,

There was a copy of that flowchart (minus the miracle/prayer bit, that's new) on one of the lockers of the technical theater majors in the dank corridors underneath the University of North Carolina at Greensboro's Aycock Auditorium. That was when I was still a technical theater major, many many moons ago, so it would be either Fall 1991 or Spring 1992. I recall it looking like a xerox of a mimeograph, so it's probably even quite a bit older than that. It's a long toothed joke in technical jobs, and I now pass it on, sometimes giving it to my service desk students in a occasional moment of levity.

I remember the "Did You Fuck With It?" flowchart from my days at Telenet, back in the dark ages of telecommunications; by 1986 it was a already a standard item in the quiver of geek cubicle humor....
