Geeky April Fools' Day Prank Roundup

Popular Mechanics and Instructables have teamed up for five pranks you can build in the office (including a stripped-down version of Gizmodo's CES TV blackout), while Wired has its top 10 practical jokes for nerds, Lifehacker is toning it down with 10 harmless geek pranks, and Slate gets you ready for the receiving end with an April Fools' defense kit.

    I've done a lot but I think my favorite one was when I was in 6th grade or so. My father usually got up at around 7:00 to take me to school at 8. I went into his room (very sneakily) and set his clock an hour forward wearing my backpack, spring jacket, etc. I then turned on the lights, woke him up and said, "Dad, you have to take me to school, I have a presentation!" and then quickly went downstairs as if I too was in a hurry. He looked at the clock (displaying 7:55) and promptly jumped out of bed frantically trying to get ready. I could have easily let it continue till we were actually at school by switching his car clock too and everything (it was a cloudy day so the sun wouldn't have been able to clue him), but I decided to let him know after he got dressed and was about to jump in the car:)

    Moral of the story:
    1) Get it in as early as possible: chances are by the end of the day they probably are more suspicious.
    2) Know your victim: my father knew how much I hate getting up early in the morning, he would find it really hard to believe I would wake up before I had to.
    3) Make it plausable: We all have at some point screwed up in setting our alarms, the scenario I created could have very well actually happened. Be mindful of details.
    4) Don't be cruel: Let them in on it after it is apparent they fell for it before they start really acting on what you fooled them with. Don't make them afraid for their life or anything crazy like that.

  21. My Favorite Prank by loafula · · Score: 5, Funny

    April, 2003. I was living in a large tent, on the Persian Gulf coast, in northern Kuwait. I returned to my cot after a hard days work, where I was greeted by a fake plastic snake. I was not surprised, due to the fact I noticed Spc Harris fighting laughter while keeping a watchful eye on me as I entered the tent.

    I am one for vengence, so my mind immediately began cooking up a scheme. The roof of the tent was made of a double layer of thick canvas material. It was sloped, at about a 45 degree angle. Harris slept with his head pointed towards the side wall, and feet pointing towards the center of the tent.

    I took my trusty knife one afternoon, and cut a slit in the bottom layer of canvas, above Harris' head, on the roof of the tent. I left the slit there, in plain sight, for two weeks thinking he would be suspicious of it at first. After the two weeks were up, I constructed a fairly large fake spider out of electrical tape, pipe cleaners and black paint. I used fishing line for it's silk. I put the spider in the roof of the tent, slightly past the slit I had cut. I then ran the fishing line over the slit, out and down the side of the tent, and finally back into the tent near my cot.>/p>

    That night after lights out, as Harris layed on his cot, watching a movie on his portable DVD player, I put my plan into action. I pulled slightly on the fishing line, causing the spider to move over and fall through the slit. I then slowly let out slack, causing my home-made monster to descend on it's web. The alignment couldn't have been more perfect, because the spider descended into the space between the portable movie screen, and Harris' face. Harris' reaction was priceless, too. Too scared to scream, he jumped from his cot, flung the DVD player across the room, knocked over a bunch of his crap, and wound up sprawled across the floor babbling "holy shit holy shit". The lights in the tent then went back on, and there was much laughter.

    I once worked at a manufacturing company, and one of the products they made was called the 5100. They needed to replace it, and there was a big debate over whether to make a software package that could run on a standard laptop, or to make another standalone device (the 5200). In the end they decided to make the standalone 5200. One of my coworkers, we'll just call him B, was strongly in favor of doing the standalone 5200; he was guy who would do the software development for the 5200, it was his baby.

    Well, I brought my laptop to work (it was a TRS-80 Model 102 if you care). In the text editor, I made a banner that spelled out "5200" in asterisks or something. I went into the lab, and pushed B's 5200 prototype to the back of his work area, and set up my laptop in its spot, turned on and showing the "5200" banner. Then I went and found B and innocently asked if he would show me the 5200 prototype. Actually, I think he was amused by the gag as well.

    Right after I was hired there, another of my co-workers tried to convince me that they had this really cool super-ELIZA program that was actually intelligent. He sat me down in front of a dumb terminal to try it out. I figured right away, correctly, that they had just set up two terminals and that somewhere else in the building, some human was impersonating ELIZA, so I tried to ask questions that would be easy for a computer to answer but hard for a human ("What's the square root of 12345?"). If only he'd had the foresight to keep a scientific calculator close at hand.

We left one clapper turned on and one turned off and both of them on the most sensitive setting. So any time there was much of a noise, half the computers in the lab would suddenly shut off, and the other half would simultaneously turn on, but there was no way to have more than half of them on at a time, and which half was on kept changing based on random noises in the lab. Teachers who taught computer classes gave up early, but half the lab was for kids on study hall, etc, and no one really warned them, so a hellacious amount of work was lost that day when people's computers suddenly turned off. They'd swear for a while, try to turn it back on, give up, and move to one of the other computers that was now on... repeat process. Of course, that wouldn't work these days, because most computers don't start themselves up when the power comes back on, but these had hard power switches, so simultaneously half the computers would go dark and the others would emit a chorus of Mac startup sounds.
