UNIQUE PRANKS
Rattlesnake Eggs>> NEW <<
Scare your victim with some "real" rattlesnake eggs! Just print out this Rattlesnake Eggs envelope and follow the easy instructions for creating the "eggs." When they open the envelope they are in for a big surprise!
There's Only One>> NEW <<
Go into your victim's closet and steal one of each of their shoes. Hide them and then laugh while they frantically try to find a match!
Word Scramble>> NEW <<
Print out this word scramble puzzle and give it to your victim. None of the words can be unscrambled into actual words! When they check the answer key hidden at the bottom of the page, they'll realized they've been pranked.
Bottomed Out>> NEW <<
Take a box of cereal, crackers, etc., and cut out the entire bottom. Set the box on the cupboard shelf and then dump the cereal or crackers straight into the top of the box (if the contents of the box came in a plastic bag, discard the bag). Close the top. Then, when your victim goes to grab the box, the contents will fall straight out onto the floor!

Holey Water>> NEW <<
Take your victim's disposable water bottle and make sure the lid is on tight and that it is completely full. Then take a small push pin and put several holes in the bottom. A small amount of water will drip out when you do this, but then water pressure will prevent any more from coming out the holes. When your victim grabs the bottle, it will either leak when they squeeze it, or water will come pouring out of the holes when they take off the top.

OFFICE PRANKS
Trap Drawer>> NEW <<
Rig a party popper to detonate when your victim opens their desk drawer. Use strong tape to attach the party popper to the inside of the desk, right above the top drawer. Close the drawer almost completely, then tape the string of the popper to the inside front of the drawer (if necessary lengthen the string slightly with another piece of string). Be sure to angle the popper so it will not explode in your victim's face.

Terrible Typo>> NEW <<
This one takes a small investment, but it's worth it. Borrow one of your victim's business cards and have it duplicated, but change one small thing--the spelling of their last name, or their job title, for instance. Sneak in and replace your victim's cards with the new ones. When the time is right, casually 'notice' the mistake. Your victim will freak out thinking they've been handing out business cards with a typo on them! (Can also be done with their resume, important projects that they've already turned in, etc.)

The Golden Rules of Pranking
Plan ahead
Don't wait until April 1st to start thinking about strategies. Early planning means you'll be ready on the big day!
Prank with love
Never pull a prank with a mean spirit in your heart. Do it to get a laugh out of someone you care about. And think twice about pranking strangers --it's generally NOT cool.
Know your victim
Pranks can have consequences--make sure to think about the outcome. After the initial surprise, will your victim's reaction be positive? A successful prank should always end with your victim laughing!
Match the prank to the person
The best April Fool's gags are carefully chosen to fit the victim's personality. For instance, a car prank is perfect for someone who is fussy about their car (but make sure you don't damage their "baby"!). Or, a computer gag will work best on someone is isn't very computer savvy. Tailor your prank for the best result.
Is it harmless? Really harmless?
Once you have your prank fully planned out, stop and think.... Is there any chance that someone could get hurt? Is there any possibility that something will get damaged? Consider all outcomes before you plot your prank!
Have the video camera ready
If you can get the moment on tape you'll be able to enjoy your prank for years to come. So break out the camera...as long as it won't raise too many suspicions!
Use your best acting skills
If you don't think you'll be able to keep a straight face, pick a prank where you'll stay hidden--or recruit a helper to be the perpetrator.
Time your reveal
Enjoy the moment, and let the prank sink in before shouting out a victorious "April Fool's!" Timing is important; you don't want to call it out too early... or too late.
If caught, be gracious
Playing pranks on April Fool's Day can be tricky--they'll have their guard up. So don't be too disappointed if you're caught in the act. You'll get 'em next time!
Be ready for retribution
Expect a payback, so watch your back!
