This might be the meanest prank I've ever seen.
A Czech guy suspected his girlfriend was snooping on his phone.
In order to catch her in the act, he sent a photo of himself with a girl who was pretending to be his side piece.
His girlfriend looked on his phone as expected.
But, what wasn't expected was her reaction. She went absolutely bonkers.
She packed a bag, stabbed his TV with a pair of scissors and stormed out of his apartment.
Soon after, the guy caught up with his girlfriend and explained it was all a prank, but she was still completely upset. And I have to say, I don't blame her at all.
