A daunting task to find an apocalyptic short story

[redcrow309]

I would like a bit of help in identifying a story I that read about two years ago, it was a free online short story.

The premise was: Some friends decide to pull a prank on a paranoid friend, by making him believe that there had been a nuclear attack, the friend starts acting strange and living like it is the end of the world by making fortifications on his roof, welding armor onto his car and killing peoples pets in the park for food.

I found the story quite amusing and I wanted to use it in a middle school lesson plan to help spark student's interest a technology class. It would give me a quick and humorous way to introduce the students to concepts such as alternate futures, technology dependency, and technology based disasters. It would open up the subject for a wide range of discussion and it also gives some of the students in the class a taste of reading material that may interest them more than what is currently offered in literature classes.

But its hard to read the story if I cant find it, and I have searched for near 5 hours to no avail. Any help in finding this story is appreciated, any bit of information; author, title, or link would be a huge help. Thanks in advance

Not sure if this is helpful or not but Doctorow publishes many of his works online.
