It is a Fool's Day!

15 April Fools' Day pranks to play on your colleagues and family or fellow students - if you dare

Take revenge at the office, at home or out with friends on the one day it's socially acceptable to do so with these

ideas for April Fools jokes

The one day it is totally acceptable to do awful things to the people you care about and get away with it because of some

bizarre medieval tradition. Remember that doing any of the following pranks after midday on 1st April is against the rules

(although, let's face it, who cares) and if you're not sure a colleague will see the funny side, it's probably best not to bother.

But if you're looking to have a laugh at someone else's expense, you could do worse than to try these effective and

inventive pranks. Just don't blame us if you lose your job/spouse/get kicked out of the house.

1. The toothpaste treat trickThis is just sick. Funny but sick.

Buy Oreos for the office. Then laugh at their bewildered and disappointed faces as they realise you've filled their biccies with toothpaste.

You MONSTER.

2. A-mayonnaise-ing prank

Try to soothe your angry colleagues with some nice fresh doughnuts after the Oreo toothpaste incident.

But replace the custard filling with mayonnaise. Maybe hide in the toilet for the rest of the day.

3. Or don't hide in the toilet, but pretend to instead

Simple, yet effective

4. Pure evil

Maybe attach an air horn to the toilet wall while you're hiding to give unsuspecting people - and everyone else in the toilets - a shock when they open the door.

Obviously DON'T do this to anybody with a heart condition.

5. Make them think their screen is cracked

Bwa ha ha! Find and download a reasonably high-resolution image of a cracked screen. Searching on Google images should give you

lots of options, or you could just use the one here.

Set the image as a screensaver on their computer, making sure it is set to activate after a short amount of time (30 seconds or so).

If you colleague uses a desktop computer rather than a laptop, you could make the prank more convincing by unplugging their keyboard and mouse.

6. In an English keyboard garden

... and you've got an eco-keyboard.  Oh no he didn't! Maybe grab an old keyboard for this one.

7. Hide a dictaphone playing a repetitive sound somewhere in the office

This one is fairly self-explanatory. Make a long recording of some kind of repetitive sound played on a loop on your computer.

Clicking, beeping, whirring and whistling all work great. Set the dictaphone playing and then hide it at the back of a drawer,

behind a filing cabinet or somewhere else tricky to find.

Watch your colleagues slowly lose their minds as they struggle to locate the source of the noise.

8. Or... "Drink, feck, girls"

Change a friend's text alert to a 10 second long clip of Father Jack from Father Ted.

Then text them every 10 seconds for around a minute or two when you know they are in a public place.

9. Light crawler

You can order these online or simply make your own (out of something non-flammable, naturally).

Creepy crawly prank

10. Automatically replace words in documents with hilarious substitutions

This works in either Microsoft Word or Google Docs.

If you're using Google Docs:

Go to tools → preferences. Replace some of your colleague's commonly used words with some 'interesting' substitutions.

In Microsoft Word:

Go to tools → AutoCorrect options. Do exactly the same thing.

Watch your colleague tear their hair out trying to type the words they actually want and avoid any bloopers.

11. (Temporarily) render their mouse unworkable

Blind mouse

This one is deviously simple.

Just stick a little bit of tape over the laser on the bottom of the mouse and it will stop working. Most people won't think to turn it upside down and look for a good long while.

12. Put their stapler inside a jelly

Well, it was funny when it happened in The Office...

13. Phone cruelty

Take a screen shot on their phone of their homepage, then remove all of the apps from their homepage and set the screenshot as the background.

They'll be trying to click on their messages icon or their Facebook icon in order to open the apps, without realising that it's actually just a picture.

14. Peanut cruelty

Film yourself sucking the chocolate off from chocolate-covered peanuts. Give your mates a bowl of peanuts (they don't have to be the same ones).

Next show them the video when they're finished for instant horror. !!! Don't do this to people with allergy to peanuts !!!

Run.

15. Stock scrub

Do you have a detachable showerhead? Screw it off, pop in a stock cube and leave it for your flatmate or long-suffering partner.
