21 Funny Easy Pranks on Your Boyfriend That Are Harmless and Hilarious

Pulling a prank on your boyfriend doesn’t mean you’re trying to start a prank war—it just means you’re having fun and adding a little mischief to your relationship. When done right, funny easy pranks on your boyfriend can make both of you laugh, shake your heads, and share a moment you’ll both remember. Here’s how to pull off clever tricks that won’t get you in trouble (well, not serious trouble).

How to Prank Your Boyfriend Without Crossing the Line

Before you dive in, here’s the golden rule: always keep it playful. Pranks should be funny, not cruel. You’re going for “Oh my god, really?”—not “I can’t believe you did that.” Avoid anything that damages trust, property, or feelings. The best pranks are the ones that are easy to reset, clean up, or laugh off together five minutes later.

1. The Endless Alarm Trick

Set five different alarms on his phone for random times in the early morning—like 4:23 a.m., 5:11 a.m., 6:02 a.m. Bonus points if you label each alarm something weird like “Time to adopt a llama” or “Check the basement for ghosts.” Just be sure to help him reset them afterward.

2. The Frozen Cereal Gag

Pour a bowl of cereal and milk, add a spoon, and stick it in the freezer overnight. Serve it like it’s breakfast in bed. Watch as he tries to dig into a rock-solid breakfast brick.

3. The Voice Assistant Confusion

Change the name your phone’s voice assistant calls him. Instead of “Ryan,” try “Your Majesty” or “Banana Boss.” Then ask the assistant to call him while he’s around and pretend you have no idea why it says that.

4. The Mismatched Shoe Swap

Quietly switch one of each pair of shoes in his closet. When he’s in a rush to leave, he’ll wonder why his sneakers suddenly feel lopsided.

5. The Soap That Won’t Lather

Paint his bar of soap with clear nail polish. When he tries to use it, it won’t lather at all. He’ll keep rinsing, scrubbing, and questioning reality for a while.

6. The Reverse Text Prediction

If you can sneak into his phone settings, change his keyboard’s text replacement. Turn “yes” into “no,” “okay” into “I am Batman,” or “hi” into “I can’t stop thinking about cheese.” Watch the chaos unfold as he tries to text like a normal person.

7. The Upside Down Everything

Flip all the icons on his desktop or rotate his phone screen (if the orientation lock is off). Also, flip the screen wallpaper upside down for a double hit of confusion.

8. The Color-Changing Showerhead

Stick a few drops of food coloring in the detachable showerhead (only if it won’t stain). He’ll step in expecting water and step out looking like a Smurf. This one’s best saved for weekends… and forgiving boyfriends.

9. The Remote Control Block

Cover the remote’s sensor with a small piece of opaque tape so it doesn’t work. Then sit calmly beside him as he smacks it, points it in every direction, and changes the batteries. Keep a straight face. It’s essential.

10. The Unexpected Playlist

Create a playlist that looks like his favorite songs, but halfway through it includes random tracks like “Baby Shark” or dramatic opera music. Sync it to his car or Bluetooth speaker and wait for the confusion.

11. The Reversed Hoodie Sleeves

Turn the sleeves of his hoodie inside out and hang it back in the closet like nothing happened. When he throws it on in a rush, he’ll struggle like he’s suddenly forgotten how arms work.

12. The Airhorn Under the Chair

If you’re feeling bold, tape a mini airhorn under his computer chair. The next time he sits down—it’s surprise time. Warning: may result in a startled jump and wide eyes.

13. The Sticky Note Avalanche

Cover his workspace, laptop, or car interior with sticky notes. Write silly love notes or doodles on a few to soften the prank. It’s funny, colorful, and wildly Instagrammable.

14. The Autocorrect Sabotage

Similar to text prediction—go into his phone’s autocorrect settings and change harmless words like “the” to “potato.” He won’t know what hit him until his texts start sounding bizarre.

15. The Inverted Bed Sheets

Make the bed—but layer the fitted sheet on top and tuck the top sheet underneath. When he climbs in, he’ll get tangled and confused, wondering how it all went so wrong.

16. The Talking Toothbrush

Record a voice memo on your phone, then hide your phone near where he brushes his teeth. Play the voice message right as he’s brushing: “You’re doing amazing, sweetie.” Confusion + foamy laughter guaranteed.

17. The Fake Bug Surprise

Buy a few fake plastic insects and hide them in unexpected places: inside his shoes, behind the shampoo bottle, or in his snack drawer. Just be ready to explain… and run.

18. The “Broken” Screen Protector

Apply a fake cracked screen protector to his phone while he’s asleep or in the shower. Act super apologetic when he notices. Then reveal the prank before he starts Googling repair shops.

19. The Bathroom Mirror Message

Write a spooky or silly message on the mirror using a cotton swab dipped in soap. It won’t show up until the bathroom gets steamy. Bonus if he thinks it’s a ghostly message from beyond.

20. The Toilet Paper Switch

Unroll a bit of the toilet paper, draw something funny or write a fake fortune halfway through, and roll it back up. It’s weird. It’s random. It’s low effort. And it works.

21. The Confetti Explosion (Mini Version)

Tape a small envelope of confetti inside a cupboard door or on the back of his closet door. When he opens it—boom! Confetti shower. Keep it minimal unless you want to be vacuuming glitter for months.

Bonus: How to Take the Joke Well

When he eventually gets you back (and he will), remember this: take it with the same humor you gave. Laugh, snap a photo, and maybe start planning your next counter-prank. It’s all in good fun—as long as it stays fun.

Final Thoughts

Funny easy pranks on your boyfriend should make him smile, roll his eyes, and say, “Really?” in the most affectionate way possible. Keep it light, avoid anything mean-spirited, and always be ready to clean up your own glitter. Mischief managed.
