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.

Making a Scene on your Wedding Day

Your wedding day is one of the most important days of your life that you will hopefully cherish forever. What could make it more memorable than your sister showing up in a T-Rex costume? Apparently, the bride gave her bridesmaids the freedom to choose whatever they wanted to wear to the wedding.

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.

Little Sister to the Rescue

While the little sister didn’t mean to, she actually pulled a pretty good one over on her older sister. The 11 year old was commenting on her sister’s work’s Instagram to try to convince them to give her a raise. After all, what are sisters for?

Help!

You would think weddings would be off-limits for pranks between siblings, but really there is no time that is off-limits for siblings to play a practical joke on each other. The brother of the groom knew that the bride and groom would kneel at the altar on their wedding day.

The First Look

It’s bad luck to see the bride in her dress before the wedding day, so lots of couples have the ceremonious “first look” where the groom can finally see his beautiful bride-to-be! But imagine you’re ready to turn around and see the love of your life when you’re met with your brother in her gown!

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!

A Gift you Have to Work for

This person got their little brother a huge LEGO set for Christmas. While that is very thoughtful, they had to make sure it wasn’t too easy for their brother to open it. They wrapped every single tiny LEGO set piece individually.

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.

They Have to Learn Young

You’re never too young to start pulling pranks on your sibling. It’s as if kids are born with an instinct to play jokes on one another. In this hilarious example, the little sister decided to steal the stool right out from under her brother.

Ruthless Toothless

You can always count on your siblings to make you smile, especially in the hard times. This lady had a tooth situation that she couldn’t get fixed during the pandemic. You would think that the bright side would be that she could wear a mask to cover the missing tooth in her smile.

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.
