So, I'm thinking of doing a video on my favorite computer pranks for April fools day. Two I'll cover are:

Desktop screen shot as desktop background
Edit hosts file to redirect popular sites

and I'll mention my Ettercap Filter, changing a printer's LCD screen's language, etc. What are some other good ideas?

[gloomer]

LAWL! The taking a screenshot and setting it as the background is hilarious!

I had so much fun with that before. I did it to my friend.

I just stopped him from reformatting

We used to press and hold Windows button+E when someone was away from their pc and had it locked, when the got back and unlocked it there would be over 300 explorer windows opened making the pc slow as hell.

Kinda off topic but my friend and I are thinking of sending out some fake letters at our school informing of random drug testings and stuff for April 1st.

And none of the people who I have done the fake background prank to actually freaked out or anything. They all figured it out pretty quickly.

Thats some funny shit.

You can make a script or execute the following command manually:

rundll32.exe user32.dll,SwapMouseButton

note: executing a second time will not reverse the mouse buttons back to normal and can only be done through a restart or control panel. You can make this a lot more fun by using some more rundll32 commands (like an infinite loop that resets the mouse pointer to certain position ) A more black hat addition is to make this run every time the user starts the computer but this will make them

I like the editing the hosts file for some fun, but a lot of people I work with would check that if Google started lauching Yahoo. So instead what I like to do and confuses a lot of people is to create a shortcut to some program like Calculator, and put it on your desktop, rename the shortcut "www.google.com" no quotes and then make it hidden, and make sure the show hidden files is not checked. Now when the person goes to www.google.com it will launch calculator instead of going to google. Combine this trick with the hosts file trick and you could have some fun results.

[riscphree]

Our office isn't open on April 1st so nothing cool will go down, but I do think I'll edit some people's hosts files now that I think of it.

I like to switch a couple of keys on the keyboard, such as N and M. On most modern keyboards they'll just pop out. Depending on how good of a typist the person is, it may take them a while when they suddenly realize that "M" appears whenever they type "N". It'll drive them crazy, they'll be unplugging the keyboard, rebooting, etc.

Also, if they walk away from their computer for a minute, CTRL-ALT and one of the arrow keys will often flip the screen upside down, sideways, etc., depending on their graphics card and drivers. Try it out, you can flip the image on the screen all around.

How 'bout sending a letter claiming its from the RIAA to you school threatening a lawsuit for illeagal music downloading.

EVIL

[SiDaFaLiCKNo]

Send them a letter with baking powder in it and "ANTHRAX" written all over it.

LoLz...That would be really funny.

[xGERMx]

Ok, I don't know how much of a "prank" this is but, I always get a good laugh out of just barley unplugging someones mouse and keyboard when they're away.
The key is to make it look like it's plugged in but, only push it in half way.

This, in combination with a fake virus has some potential laughs.

Maybe send a fake email earlier in the day warning about some new virus or something...

Most people that use myspace are complete idiots and oblivious to host file modification.


Redirecting myspace to goatse - priceless.

Jason's best line in the article,

The fact that I used the deadly spell "mv" to shift a few things around on a machine I own is not a possibility as far as Motorjames1 is concerned. Next, just to make sure all bases are covered, he threatens me. Ostensibly he is indicating he will punish me by doing something traumatic to my ass.

That or parts about the pilots of Gen Y being unable to do anything about the Goatse "flodding".

Yes, I remember some classic programs:

"small penis window"

-make cursor move in opposite direction
-make cursor not come to a stop when you stop the mouse
-keyboard remapping
upsidownternet

-caller ID spoofing + social engineering FRIENDS: "hello, John? This is Julie (voice changer!) with Cingular Customer Care. We're calling regarding your account....as it stands, we show that you have outstanding charges of $13,000 on your bill and we need payment at this time before you can make further use of our service." Much LULZ and hilarity ensue!
