Pranks at work can be great, as long as they are harmless and funny.

What would you do if you heard two coworkers discussing some coins that they found on their desk, but they didn’t know where they came from?

That is what the woman in this story overheard, and that is what started a prank that has been going on for weeks. She keeps hiding coins in various places for those two coworkers to find, and they are going crazy trying to figure it out.

Personally, I love this type of prank. It can make the whole office a lot more fun. Read through the full story below and see what you think about it.

Slowly driving my coworkers insane with coins

About a month ago, I walked past two of my coworkers’ desks and over heard one, Jason, ask the other, Kelsey, something. It was along the lines of, “Am I tripping or are there more coins on my desk?”

Why did she have coins on her desk at all?

She didn’t know what he was talking about, and besides a little chuckling that was the end of the story. While they were gone on break I went over to Jason’s desk to check out the coin situation.

There wasn’t a crazy amount. Just a quarter, a dime, a nickel, and a penny. I didn’t know which ones were the “more” or unexpected ones but when I reached into my pocket and realized I had one of each, I decided to leave them there on his desk. After all, it was just 41 cents.

This is a fun and harmless prank.

Even though I tried to walk past them as many times as I could that day I didn’t hear anything else. Maybe he didn’t notice. Maybe I just wasn’t there when he did.

But later I overheard Kelsey telling her friend, Becky, about it. That’s when I decided I wanted to keep messing with these people. At first I’d just add the .41 to Jason’s pile. He started stacking the coins by denomination. Every day. The same types.

How has she not gotten caught yet?

Once I left late and left it in a smiley face. Then I started hiding them a little. Under things he’d use. Sometimes a little harder to find. Under an extra monitor. Inside a log book everyone in their area uses. Under a floor mat.

Once, I had an extra quarter, so I hid it inside Kelsey’s clear pencil sharpener. I taped it under Jason’s desk.

They really have no idea who is doing it.

I’d heard Jason’s supervisor tell everyone in his area to go work on something in a different spot. I had some coins taped up in my pocket ready to go. I beat them to the area and left them to be discovered. Jason luckily found them taped to what they were organizing.

Things were getting good. They were talking to their friend, Davis, about it constantly and the three of them were definitely accusing each other of being behind it.

How much is this costing her?

Then I taped some quarters under Davis’ desk. He didn’t find those right away, so it was pretty fun when he finally did. Keeping a quarter, a dime, a nickel, and a penny on me every day was getting tougher.

I’d have to ask for specific change when I went out and bought things. I finally went to the bank and got a roll of each to keep it going. While I was there, I decided to pick up some dollar coins. They became my new calling card. But I made sure Jason always got the original 41 cents along with it.

This is becoming a mystery for the whole office.

I can walk around our warehouse pretty freely and can come in a little early and stay as late as I want, so I’ve been throwing them off as far as when it happens.

I’ve started hiding them in their usual seats for lunches and breaks. They’ve told so many people. Nearly the whole warehouse knows. Leads are trying to figure it out.

What a fun office.

Our manager is pulling out his hair trying to figure it out, but fortunately is into it. I guess I’ve been mostly working in the camera’s blind spots. It’s harder now.

Everyone is watching. I can’t stop messing with these kids though. The best part is seeing them tear apart their desks before I’ve hidden anything. Eyeing each other. Turning at every rip of tape.

Things are escalating, and I love it.

I bought my own tape to use. I bought some teen/childrens magazines to cut fun letters out of to make a ransom note style card to be found.

I’m leaving the message on a flash card with the number 41 on it.

She should keep it going as long as possible.

I’ve already got my money’s worth of enjoyment out of this. I was going to end it, but it’s been too fun.

These are the types of workplace pranks that are so much fun and don’t cause any problems. Of course, the cost could add up over time.

Read on to see what the people in the comments have to say about it.

Keep an eye on the quiet ones.

This is the perfect prank. Nobody gets hurt or upset, but everyone is trying to figure it out.

I hope she is able to continue it long into the future, even if it does cost her a bit of money.
