Joker Prank Birthday Card

Sign, seal, and deliver a practical joke that your friend won’t forget no matter how hard they try... because they’ll still hear it!

This prank greeting card looks like an unassuming birthday well-wish with a cute audio accompaniment. When your recipient pushes the button inside the card, they’ll be serenaded by a special pre-recorded birthday song.

The trick is that the song never stops! Your recipient will grow more exasperated as the birthday jingle plays on a loop. If they try to stop it by pressing the button, the music only plays louder. The only way it will stop is if the battery dies or it’s destroyed.

Happy pranking with this diabolical Happy Birthday card!
