Kevin Hart was born and raised in Philadelphia and is a die-hard Eagles fan. So when the Eagles won the Super Bowl against the New England Patriots, Hart (who was admittedly drunk) tried to make his way on to the stage during the trophy presentation. He was promptly denied by security and the whole interaction was caught on camera. After that, he managed to make his way to the NFL Network's broadcast booth and dropped an F-Bomb on live TV before running off.
You can say the end of Hart's night was a massive success.
