Trick birthday candles just got one-upped.
Enterprising California brothers Nick and Travis Peterson decided to put a new spin on birthday-specific events that don’t end when they are supposed to with their new invention, the “Joker Birthday Card.” It’s a card that plays music when you open it — except it never stops.

The brothers have already raised more than four times their initial goal of $7,500 on Kickstarter — so stand forewarned that any seemingly innocent birthday greetings you receive might actually contain a song that never ends.
