The Best Sibling Pranks that Have Been Shared Online

Siblings pulling pranks on one another is basically just a way for them to show their love. We’ve collected some of the most hilarious sibling moments that we could find online. You might even take some inspiration jokes to play on your own brothers or sisters.

Her sister took that very literally and decided to wear a T-Rex costume to the event. We hope the bride had a sense of humor about the situation. Or else she’ll be looking back on wedding photos with a dinosaur in them with bitterness for a long time.

Unknowingly, she pulled a pretty good prank on her sister who got nervous when she was called into HR. Overall, a harmless prank. And we love to see siblings who have each other’s backs! We’re impressed that the 11-year-old was so persistent.

His nephew loves the new toys and so Uncle Bryan gets brownie points with him. Plus, he gets to annoy his sister without lifting a finger. Isn’t this kind of the job of any sibling? Mission accomplished.

So, he decided to leave a funny little note on the bottoms of the groom’s shoes. He wrote “help” across them! We hope the entire family was able to have a laugh about it and that the bride had a sense of humor. We must admit it is a pretty good prank to pull on your brother.

This sibling came up with a genius idea for how to remind their sister of a less-than-flattering childhood photo. She printed it out onto a mug as a birthday gift. How thoughtful! Now, she will never be able to forget this picture exists. At least she can laugh about it!

Even with a tiara to top it all off, his brother is definitely not the bride he was planning to see. But this makes for one of our absolute favorite sibling pranks we’ve seen so far. Hopefully their laughs helped the groom shake off some pre-wedding nerves!

So when his brother opened the box ready to play with the set, he was met with hundreds of little pieces to unwrap. But who really loses in this prank? Because the sibling had to take the time to wrap each of those little pieces. Some pranks take some real commitment, obviously.

She looks totally innocent but we think she knows what she’s doing. Big brother looks pretty distressed so we’re sure he got back at her somehow. You really never are too young to start playing mischievous games with your siblings.

But her sibling had other plans. He made her a custom mask that proudly showed the gap in her teeth. There’s very little siblings love more than to embarrass each other. But if the goal was to make his sister smile, mission accomplished.

Put all together, they look almost exactly like the regular ones! Imagine receiving these as a gift and being excited to bite into a chocolate only to be met with vegetables. Yuck! They should definitely expect a prank war coming their way after this one.

But you can see it written all over her face that she can’t wait to let the hose fly and surprise her brother with a face full of hose water. What are big sisters for if not to pull pranks on their little brothers? They have to learn somehow!

But she couldn’t possibly resist adding a little joke onto the inside of the ring. She got “okayest sister” engraved on the inside just to make sure her sister didn’t get a big head about the gift. These are our favorite kinds of sibling pranks. 

But what makes it even more genius is that the mugs appear to be normal black cups until you pour hot liquid in them. Then the mugshot is revealed. This is a pretty creative way to never let your brother forget his embarrassing moments and regrets.

He promised that if she succeeded in graduating with honors he would wear a dress to her graduation. And not just any dress! He promised to wear a matching dress with her. It looks like she succeeded and he kept his promise. There’s nothing like the notion of embarrassing your brother to motivate you to work hard.

This is just the opposite. If this gift is for a younger sibling we can assume that they were none too pleased when they found batteries instead of that new toy they were wanting.

But they actually dressed the milk up to look like a robber. Very bad indeed. If this was part of a prank war, we wonder how the sibling retaliated.

Have them place their hands face down on the table and place full glasses of water on either hand. Now they’re stuck! Eventually they’ll realize that they can’t move without spilling all the water everywhere. Gotcha!

So, she chose to retaliate in an interesting way. She slowly piled bread on top of her sister’s face all while she was asleep. It looks like she got the entire loaf of bread piled and she still didn’t wake up! This is an excellent prank for a heavy sleeper.

The “guy who pays for account” must be the father and the 2 parasites are what we commonly refer to as children. This is a good one from dear old dad and it’s all in good fun. The problem is, the kids can change the account names as well so how will they retaliate?

He made folders on her computer and hid her school project in one of them, essentially holding it hostage. It’ll take her forever to find the project! I guess the lesson is to not steal from your brother, or be prepared for the consequences if you do.

When the ice melts down the mentos will mix with the soda and they’ll be met with a soda explosion to the face.

If you play your cards right you will have a perfect set up for your sibling. They’ll come home and go to sleep only to see something awfully scary peeking around the corner at them. Another genius prank!

They took different photos on each phone and ipad in the store and set them as the screen savers. Anyone who walked into the store that day was in for a big surprise.

Wrong. This sibling positioned their sister right in front of a fountain and the result is this perfectly timed photo. We’re still impressed by the yoga pose regardless!

He brought a real life llama to the wedding all dressed up and prepared to accompany the wedding party down the aisle. She doesn’t look all too happy for the added guest, but the brother sure looks pleased!

Their sibling will be met with the many faces of the actor the next time they go to enjoy a cold beverage. Points for creativity! Nic Cage is probably one of the very last things you would expect to find in your ice cubes.

This little brother somehow managed to flip glasses of water upside down on the counter. And he did this with 11 glasses! We wonder if they just left the glasses for a while to avoid cleaning the mess.

The poor skeleton is tied up and asking for help! This time he ended up in the trunk of one of the brothers’ cars. We wonder where he will end up next time.

As you can see, there were tons of family photos that now display a sloth! We wonder how long it took their sister to notice that their face was looking pretty different in the family photos.

He turned his brother’s bunk bed into a cage and basically trapped him. He will be awfully confused when he wakes up and we’re sure mom and dad won’t be too pleased. But at least it got them up early!

Now, if the sibling was actually returning from rehab we have to ask why he made that information public (to embarrass his sibling of course). But if their sibling wasn’t returning from a facility, it makes this prank even funnier. His smile says it all — he is proud of his creativity.

This way, when their brother or sister went to have a bowl, they would think the ice cream tub was full just to be met with disappointment when they open the tub. Kind of mean, but still creative.

They built this little fortress around their youngest sister. When mom came in asking where she was, they revealed this secret location. It looks like the little sister might have been a willing participant so this one makes us smile.

But siblings across the internet have also joined in the fun! This person was incredibly thorough when they tin foiled this room. Even the pillows are covered. We can only imagine how long this took to undo.
