Computer lab pranks

!!! please rate this article !!!

I have taken pride in my computer pranks, although they are simple they always seem to work and sometimes the simplest pranks are the best.

To begin with, remember that not every prank needs an elaborate script. Try
• Swapping mouse or keyboards around so they type on our computer
• Disconnecting things like keyboards is always a laugh
• If there is a supervisor or teacher there just keep shutting down your computer and watch them puzzle over it.

Now that we’ve got the basics over with lets move onto some basic scripts.

The JavaScript alert loop has to be my favorite. You can inject it into a the url/a text box or you can put it in a web page and email the link, if you are in a library with catalogue computers you can inject the script there and wait for the next person to stumble upon it, there are infinite possibilities.
For those of you that don’t know, a JavaScript alert loop is just that, it is an alert that keeps opening.

These are the scripts for looping an alert try them out and see which one you prefer.
Change the number 10 to the amount of times you want it to loop

Loop with text and number:
javascript:for (i=1;i<=10;i++) {alert(\"your text here \"+i);}

Loop with number only:
javascript:for (i=1;i<=10;i++) {alert(i);}

Loop with text only:
javascript:for (i=1;i<=10;i++) {alert(\"text here\");}

For submit form (eg. Library Catalougue search)
<script>for (i=1;i<=10;i++) {alert(\"text here \"+i);}</script>

For button on web (try putting a fake submit form and when they click submit the loop starts)
<script type=\"text/javascript\">
function doIt() {
for (i=1;i<=10;i++) {
alert(\"Fatal Error \"+i);
<input class=\"button\" type=\"button\" on<i></i>click=\"doIt()\" value=\"submit\">

Start automatically on webpage open
<body on<i></i>load=\"javascript:for (i=1;i<=10;i++) {alert(i);}\">

Lastly we have the infinite loop which is not recommended (don’t try this at home)
javascript:while(true);alert(\"Oh no, I\'m stuck\")

javascript:while(\'a\'==\'a\');alert(\"oh no, I\'m stuck\")

javascript:for(i=0;i<4;i=i;i++);alert(\"oh no, I\'m stuck\")

on to the next prank, batch files.
Batch files can provide endless entertainment if you use them properly. Usually this prank only works on people who are computer illiterate but you never know who it might fool. All you need to do is write a simple batch file that makes the user think their c drive is being deleted or something then get someone to open it (try emailing it) and watch their faces turn white.
Here is a simple one that I use put it in notepad and save as something.bat (not .txt, .bat):

@color 0a
ECHO !!!Deleting C Drive!!!
ECHO do not exit, exiting will result in total system failure
ECHO Do You want to continue with deleting your C drive?
ECHO press y for yes or n for no
ECHO you chose yes, please confirm by pressing y/n
ECHO deleting C Drive
ECHO C drive deleted
ECHO have a nice day

If you havn’t found your kind of prank above maybe you should try downloading some prank programs, my favourite site for this is (
If that doesn’t suit you maybe your not the prank type, maybe you prefer causing some real trouble with exploits etc..

Either way I hope this article has helped you and will hive you hours of fun.

The 2nd one is a great way to get banned from computers/suspended from school.
AldarHawkon September 25 2006 - 01:10:48
This was a total waste of my time. This is silly. [sercastic]I would not have know how to do any of these if I did not read this[/sarcastic] Sorry not a fan of this kind of petty games. :evil:

this wasn't supposed to be a serious article, just some SIMPLE ways to get a laugh, as i say at the end if its not your type of thing you can download some prank programs for a LAUGH if the only way you can laugh is to give someone greif by using complicated exploits. then you need to get out more.Smile

I just don't see how it is that funny. The only people that believe this don't know what the C drive is.

Go to your neighbors keyboard and slam on ALT+F4 a few times and watch the computer shut dowm =P

With the batch file, you could add it so it copies itself to the startup and shuts down the computer.

In regards to the batch file, it will be good if you include the 1% - 100% completed. That will make it more realistic since I cannot imagine that files on my C drive will be deleted that fast. B)

this is alot of fun suggestion though just change the numbers so they countdown javascript:for (i=10;i>=1;i--) {alert("System Failure in... "+i);} like that so that in this case the message comes up saying System Failure in...10 and then countdown probably more worrying for the person you do it to this way Grin
