According to the video's caption (written by the account PoliceActivity) a college junior in Arkansas was pulled over for having a taillight out and driving extremely slow through campus at night. The officers quickly determined that the student wasn't actually impaired at all then issued a toungue-in-cheek "test" to check out his juggling skills.
Needless to say, this guy didn't disappoint! I figured anyone with a license plate like his better be at least decent.
