If your friends and family are throwing you a baby shower and are known for playing pranks, maybe watch out for one of these cards.
Travis and Nick Peterson, the brains behind
Joker Greetings, have created a trick card that will (ahem) prepare soon-to-be parents for their new arrival.
That’s because when you open it and press a button, it blasts out the sound of a newborn baby crying.
Apparently it keeps going until the battery runs out (that is said to take approximately 3 hours) or until someone breaks it.
According to the
Huffington Post, closing the card makes no difference and pressing the button only makes the volume of the cries louder.
