Here's a slightly less common variation of the Idiot On The Field phenomenon: Idiot On The Court.

According to various reports on Twitter, a fan at tonight's Cavs game against the Clippers found his way on the court and was apparently wearing a shirt with a special message for Kyrie Irving: Kyrie Don't Leave. That'll keep him in town and definitely won't creep him out when you walk up to him on the basketball court and open up your jacket like some kind of G-rated flasher.
