There are some things you should probably never joke about with your girlfriend. Cheating on her is easily right there at the top.

Watch prankster Roman Atwood get the shock of his life when he jokingly tells his girlfriend of five years that he cheated on her (during their anniversary trip to Aruba!), only for her to break down and reveal she had cheated on him, too!

Luckily, there's a happy ending to this seemingly horrible story: she didn't actually cheat on him. After basically giving him a heart attack, she reveals she had seen him setting up the hidden camera and knew something was up.

Whew -- we almost had a heart attack, too!
