He's been called the worst boyfriend in the world. In the video below a man sneaks into his girlfriend's apartment to pull a prank on her. When she and her sister arrive home they think someone is robbing them and run out screaming. While this may not be the worst thing a guy can do to his girlfriend, it might rank up there as one of the dumbest. Had this happened in Texas, there is a good chance the guy would have been shot by one of the girls. So, tip to guys out there, don't do what this guy did.
