Classic Costume Switch-Up

This one is a timeless in the world of stag do prank ideas. Convince the groom that the stag do has a costume theme — perhaps superheroes, movie characters, or even animals.

Once he shows up in his full-blown outfit (imagine him as a giant banana or ballerina), surprise him by revealing that everyone else is in regular clothes. The contrast will be comedy gold, especially in public places.

Fake Tattoo Appointment

Book a faux tattoo session with a convincing setup and an artist who’s in on the joke. Let the groom browse through bizarre designs and sit in the chair nervously while everyone encourages him to commit.

Right before the needle is about to hit skin, reveal the prank and offer him a temporary version instead. Bonus points for giving him a hilarious temporary tattoo to wear for the rest of the trip.

Celebrity Meet-and-Greet Hoax

Set up an elaborate ruse that the groom will meet his favorite celebrity or sports hero. This can involve fake emails, planted clues, or even a staged photo op.

Arrange for a professional lookalike to make the big entrance – or even a friend in disguise. Keep it lighthearted and be ready to capture his reaction on camera — priceless!

Celebrity Message

While we’re on the subject of celebrities, getting a personalised message from a celebrity on a platform such as Cameo could be a great stag do prank idea, and can be surprisingly affordable especially if a group are splitting the costs. Be sure to include references to specific jokes or embarrassing moments for the celebrity to refer to in their message!

Drag Queen Stripper

He’s agreed to a stripper…but he’s left the rest of the details in the capable hands of his best man. Watch his face when he realises you’ve booked a drag queen for the occasion!

QR code prank

This is a great one and so simple to do. First, decide what you want the QR code to link to. It could be an embarrassing video of the groom you’ve uploaded, or even just the classic Rick Roll. Next, create a QR code that links to your material using a free online QR code maker or Canva.

Next, decide what you are going to put the code on to make the groom scan – such as a fake bar flier advertising a free drink, a lanyard with the groom’s face on it, or simply a sticker saying “scan me”.

This prank has maximum impact if you print off a bunch of the stickers or fliers and watch as random strangers in the bar get to watch the groom’s embarrassing video!

Early Morning Wake-Up Call

There’s nothing quite like starting the day with confusion. Wake the groom up at an ungodly hour with a fake emergency, like a missed flight or mysterious interview. Make it even funnier by dressing him in something ridiculous during his groggy state and dragging him outside for a fake event or “press conference.” He’ll laugh — eventually.

Stag Do Arrest

With the help of an off-duty cop or an actor, stage a mock arrest for a minor (and fake) offense like impersonating a karaoke singer. The prank must be clearly safe and revealed early enough to avoid panic, but if pulled off well, it will become the stuff of legend. Always ensure this prank is light and legal.

The Wrong Hotel Room

Give the groom a key to a different room filled with absurd decor. Think creepy doll collections, bizarre art, or framed photoshopped pictures of the groom in ridiculous outfits. When he walks in expecting a nap and finds a haunted house or his “childhood bedroom,” the reactions are golden.

I’ve chocked myself

One of the legendary level stag do prank ideas…When the groom to be is asleep (or passed out), slip a chocolate bar such as a Mars bar between his cheeks (you know we’re not talking about his mouth here!) and watch his expression on waking. He may well “choc” himself for real!

The Wallet Swap

Swap his wallet for a gag version filled with Monopoly money, baby photos, fake IDs, or a “membership card” for a made-up club like the International Lovers of Crocs Society. Watch his face when he tries to buy a drink or flashes it unknowingly.

Karaoke Sabotage

Secretly enter the groom into the karaoke lineup with an embarrassing solo — maybe a dramatic ballad or a Disney classic. Make sure the crowd is cheering him on while he belts out a tune he didn’t know was coming. Even better: film it for the wedding slideshow.

Groom Roast Awards

Plan a mock awards ceremony where the groom receives titles like “Most Likely to Cry at the Altar” or “Best Dressed for a Bar Fight.” Give out joke trophies or sashes and let each groomsman present their award with a short speech. It’s great for bonding and brings lots of laughs.

Fake Tan Fan

Swap the contents of his shower gel or moisturiser for extra dark fake tan and see how long it takes him to realise he now resembles Ross from Friends in that episode…

Shot Luck

If there’s a particular spirit or liquor your groom always drinks, swap out the contents of a bottle with another that is the same colour, for example swap vodka for gin, or whisky for brandy. Even better if you swap it for something he hates!

Mystery Guest

Invite someone unexpected from the groom’s past to record a video message — a strict teacher, former boss, or an old crush (all in good spirits). Their appearance should be friendly and humorous, giving the groom a hilarious surprise and everyone else a chance to see him squirm — affectionately, of course.
