How To Freak Out A Ref, By Illini Quarterback Nathan Scheelhaase

Either that referee really didn't want to seem like he had a conflict of interest by high-fiving a player from one of the teams, or he's a germaphobe. Considering it's probably the former, we now know every ref's kryptonite—run after them with your hand up and they'll walk over their own mother to get away from you. We encourage all players at every level to use this knowledge to makes referees uncomfortable.
