A guy in a LeBron James jersey tried to crash the Golden State Warriors championship parade in Oakland on Thursday morning, a feat that was short-lived as it didn't take too long for the crowd to catch up to it and boo.

The rivalry is real.

In a sea of blue and gold, a wine-and-black Cleveland Cavaliers jersey is sure to stick out and surely not sit well with the Oakland faithful, who are sure to soak in this championship parade with the imminent move to San Francisco in a couple of seasons.
