To celebrate their son-in-law's 40th birthday, one couple decided to send him a quirky, creative card - and they nailed it. The cleverly written card features an image of their son-in-law's face on the front, with the words "Happy Birthday Son-In-Law!" printable underneath. On the back, they've included some fun facts about him - like his zodiac sign and favorite food. And at the very bottom of the card, they've even included a QR code so that anyone with a phone can read the bio in full!
