Everyone gets bored at work sometimes; it’s part of life. Next time you get bored in the office, however, instead of drawing a mindless doodle consider enacting one of these office pranks.

An office prank is great for spicing up a boring old workday in a harmless way. Most of the time you don’t even have to buy anything because you can find all the supplies you need to pull off a prank right in the office.

Ready to pull off the prank of the year that everyone in your office will remember? Then read on to learn all about the best office pranks and everything you should take into consideration before setting one up.

What is an Office Prank?

An office prank is a fun joke you play on your unsuspecting coworker(s) to have a little fun during the workday. They can be pulled off in the break room or in the office itself.

Office pranks are meant to be pulled in a funny way that makes everyone laugh, even the coworker you are pranking. You can only accomplish this if any funny office pranks you plan are harmless and do not cause damage to any office property.

Additionally, ensure the prank is positive and not mean to your coworkers. Never do illegal stuff when pulling off an office prank.

If you are a supervisor or manager, you can get in on the office pranks too. In fact, many managers having a little fun with their employees from time to time can boost employee engagement and help everyone work as a team.

Things to Think About Before Doing Office Pranks

The only thing worse than a boring office is one filled with angry coworkers. So, before pulling any office pranks, there are some things you need to think about.

For example, you wouldn’t like it if your little prank got you fired, so ensure everything you plan to do is in your employee code of conduct.

You also need to ensure that the prank is funny for the entire office and that not even one single coworker could take the prank the wrong way. Otherwise, they could be upset and cause problems.

Sound like a lot to think about? Really it isn’t so hard at all, just follow these ground rules:

  • Don’t destroy the office property or the property of others
  • Don’t physically hurt anyone with your prank
  • Always obey the law or the workplace rules
  • Don’t design a prank that involves protected groups of people
  • Plan your prank so it doesn’t disrupt the entire day

If the prank you have designed meets all of the above requirements then it is probably a good prank to pull.

Be aware that while pulling the fire alarm may seem like a good office prank, this is illegal and can result in personal fines as well as fines for your business.

  • Funny/weird photos in a variety of shapes and sizes (they can be animals or superheroes or whatever you want)
  • A day you can come to work before your co-workers

Locate family pictures on each desk, and open the frame, slipping your image on top of their photo.

What You Need:

  • Duct tape

What You Need:

  • Plastic Wrap (multiple rolls)
  • A co-conspirator to help

Step 1: Find out Where Your Coworker Parks

You may need to ask around a bit to see what type of car your coworker drives and where they park it. You may also need to stake out the parking garage to be sure.

Once you know what their car looks like, and know your coworker is in a meeting or busy with a call, head down to the garage with your supplies.

Step 2: Place the Spider/Snake

Place the fake bugs or fake snakes (or both) in the desk drawer your coworker is most likely to use.

Step 3: Ask for Something

Either wait for your coworker to open their drawer, or ask to borrow something you saw in there. Either way, prepare for a shriek.

What You Need:

  • Ice Cube Tray
  • An iced beverage to share

After the main item you want to rubber band is done, start rubber banding items that would help your coworker remove the rubber bands, such as their scissors.

You may also want to rubber band their stapler, tape holder, and other things on their desk they probably need.

Once you are finished head back to your desk but keep an eye out for your coworker’s frustration at discovering just what you’ve done.

Talk about this new coworker with anyone who will listen. It may help to get others in on the prank to make it more effective.

Continue talking about the fake new coworker until someone in the office asks about him/her. If they just start talking about the fake coworker too, then you’ve officially fooled them all.

Log back into zoom, but change your name to match that of your coworker. Now there will be two of you and you’ll look the same too. Stay quiet until someone notices then have a nice laugh.

What You Need:

Funny birthday cards left on their desk is also a great addition to this prank.

29. Filled with Balloons

Balloons are always good to have on hand for a prank. Whether you want to prank your boss, or anyone in your office, this one is harmless and fun for all.

What You Need:

  • Balloons
  • Strong Lungs (or a Partner)

Step 1: Decide Which Room to Fill

For this prank, you will be filling a room in your office with balloons. Conference rooms, or a bosses office work best. Try to find a time when the room will be empty for a significant period of time.

Using the power of your lungs fill all the balloons you can with air. If you have access to a supply closet, you can even start this step a couple of days in advance.

Step 3: Fill the Room

Once the balloons are filled, put them in the room you decided on and wait for someone to discover the room they want to use is filled with balloons.

30. Stuffed with Stuffed Animals

Most office tricks are cheap, but this next one could be costly unless you have a bunch of old stuffed animals lying around at home that your kids don’t mind you taking. Just know that these should be stuffed animals they don’t expect back.

What You Need:

  • Stuffed Animals

Step 1: Decide Which Room to Fill

Decide which room you will stuff with stuffed animals. It should be a room that is left unattended for long periods of time.

Step 2: Wait for the Room to Be Empty

Once the room is empty, grab your stuffed animals and stuff them in. It can be helpful to start collecting stuffed animals in advance and storing them in an unused closet until the time comes.

Place the stuffed animals on every surface possible, also leaving a bunch on the floor.

Step 3: Wait for Discovery

Chill nearby and wait until someone discovers that the room they want to use is currently occupied with stuffed animals.

31. Office Pall Pit

Pranks where you fill a space are just so easy to execute, and the ball pit prank is fun for all involved. You’ll need just a few supplies to carry out this fun prank.

What You Need:

  • Plastic balls (at least 1000)
  • Saran Wrap or Plastic Kiddie Pool

Step 1: Build the Pit

The Ball Pit prank is best carried out in an office with cubicles. You use the saran wrap to cover the door to make the pit.

If your office doesn’t have cubicles, don’t toss aside this plan just yet as you can use a kiddie pool as the pit. Wait until your coworker heads out to lunch to build the pit.
