Forget candles and confetti. This officially licensed Garbage Pail Kids birthday card serenades the birthday person with our original "Happy Barf Day" song — performed by a guy who clearly ate way too much cake and is about to lose it. He sings, he gags, he sings again. The song is "Happy Birthday" reimagined as the worst birthday party you've ever been to. And it plays on a loop, for hours, until the battery dies.
If they grew up trading Garbage Pail Kids at recess in the 80s or 90s, the artwork alone is going to send them. If they didn't, they're about to meet the most beloved gross-out brand in trading-card history. Either way, the moment they open it, the queasy crooner starts singing — and doesn't stop. For anyone with a GPK mindset, a sick sense of humor, or both.
How the Endless Musical Card Works
- Open the card to test the sound, sign your message, then close the card to stop the sample.
- Insert the card into the envelope and pull the tab from the spine to arm it.
- Once they open the card, "Happy Barf Day" loops non-stop — even if they close it — and plays for hours, until the battery dies.
- Inside, a pull tab labeled "Peel Here for a Surprise" releases a chunky glitter explosion and a pack of 5 Garbage Pail Kids stickers.
*Plain white envelope included
Inside the "Peel Here for a Surprise" Tab
Five officially licensed Garbage Pail Kids birthday stickers, plus a chunky glitter mess that's exactly as messy as it needs to be — no more, no less:
- Happy Barf Day — the cover star, mid-yack.
- Potty On! — a toilet character ready to celebrate.
- Sick! — a punk rocker who came to party.
- Treat Yourself — because it's their day.
- Bite Me — a birthday cake character with attitude.
Officially Licensed Garbage Pail Kids Artwork
Every illustration on this card and every sticker inside features authentic Garbage Pail Kids artwork. We worked directly with GPK to bring the legendary gross-out trading card brand — slimes since 1985 — to the birthday card aisle. This is the real deal for collectors, 80s and 90s kids, and anyone who grew up trading these at recess.
Great For.
- For the GPK collector — they have the trading cards. They don't have this.
- For the friend with a sick sense of humor — finally, a birthday card that matches their personality.
- For an 80s or 90s kid's milestone birthday — 40th, 50th, the years where nostalgia hits hardest.
- From the kids to a parent — and yes, this is exactly the kind of card a kid would pick out, which is what makes it perfect.
- Office birthdays, white elephants, gag gifts — anywhere a normal card would be too polite.
Frequently Asked Questions
How long does the song play?
Once activated, the card plays continuously for 3 to 6 hours until the internal battery dies. There is no off switch. Please note; batteries are like a sponge so if they open it again you'll get more music.
Can I sign the card before it activates?
Yes. You can safely sign the card and it will play one-time. Close the card and it will stop.
How do I activate the card?
We suggest inserting the card into the envelope first the remove the instructional tab from the spine. The moment your recipient opens the card, the song (or sound, depending on your design) starts playing automatically and won't stop until the battery dies or it's broken.
What stickers are inside the GPK Birthday card?
Pulling the tab reveals 5 exclusive Garbage Pail Kids birthday stickers: Happy Barf Day, Potty On, Sick, Treat Yourself, and Bite Me. Plus a chunky glitter explosion.
Is this an officially licensed Garbage Pail Kids product?
Yes. Joker Greeting is an officially licensed partner of Garbage Pail Kids. All artwork featured on the card and stickers is used under an official license from Garbage Pail Kids / Topps.
How do I stop the song?
Once activated there is no off switch. The song plays until the battery dies. Attempting to destroy the card triggers the hidden glitter (or in some cases the glitter is found when the pull strip is removed). That's the prank.
