Scavenging Fool
Borrow a favorite item belonging to the victim. Take a photograph that shows the item in an easily-identified locale (by the fireplace, in the mailbox, on the washing machine, etc.). Leave the photo where the victim will find it. When they go to the location shown in the picture, arrange it so they find another picture of the item...this time in a NEW location. Continue this as many times as possible, until at last they are rewarded with their item, with a note that says "April Fools!"
Bright and Early
Unscrew the shower head and put some Kool-Aid powder behind the filter. The victim will be surprised when a bright, sticky mess comes pouring down. (Or, for another way to accomplish the same prank, put a piece of hard candy in the shower head.)
Sweet Success
Make some "delicious" caramel apples. But trick your victim by substituting an onion for their apple!

Squeeze Play
Use glue to block up the opening of the victim's toothpaste, and then cut several slits in the lower part of the tube. When they go to brush their teeth, they will get their hand covered in toothpaste.

Just Gross>> NEW <<
Take a disposable baby diaper and smear a large amount of melted chocolate in it. Then place it face down stuck in the middle of victim's car windshield. When they see the mess they'll be grossed out!

The Run Around
Set this prank up ahead of time by letting the kids know you're planning on having some painting done in the house. Then, before they come home from school, put up two signs: on the front door - "Wet Paint - Use Back Door," on the back door - "Wet Paint - Use Front Door." Then see how many times they'll run around the house trying to get in.

Forgetful
Tape magnets to the bottom of an empty coffee cup, and attach it to the top of your car. Laugh at all the people who frantically try to get your attention as you drive by.
Big Winner
Buy a lottery ticket and give it to the victim on March 31. The next day go out early and buy another ticket with the exact same numbers as the WINNING numbers from the day before. Put this ticket in the place of the ticket from the day before. Wait for them to check the numbers in the paper. They probably won't notice the different date, and will think they just became a millionaire!
