Never-Ending Birthday Card Despite everyone's best intentions, birthdays are inevitably a stressful affair. All the attention, the candles, the singing, the pressure. Why not take things to the next level and get them the Never-Ending Birthday Card

A birthday card like no other, treat your loved ones to a gift they'll always remember. Because they wont have a choice. Because it never stops playing. Give them the gift of a permanent ear-worm combined with extreme mental anguish. Don't worry, there's a safety tab so you can sign the card and test it before the fun begins.

Once opened, the Never-ending Birthday Card continues to play for up to three whole hours (though the one we foolishly tested played for five!). The music gets even louder if they try pressing the button inside to stop it, heck they can submerge the card in water – this relentless beast just keeps on jingling. Best of all, when the lucky recipient finally reaches breaking point and tries to rip into the card to destroy its circuitry they'll be greeted with a merciless explosion of glitter.

Needless to say, this is the best prank birthday card in existence.

Word to the wise:

• This card arrives packaged and needs to be opened and signed first before gifting
• Send it to yourself first before giving it to your unfortunate recipient
