WORST THINGS YOU'VE SEEN AN UMPIRE DO

The worst I have see was about 15/18 yrs ago in a 13/14 PONY game. The PU was a self-proclaimed rules expert but was in reality an idiot. Ball was hit to RF deep, the BR comes into second on a stand up double. The ball is relayed into F6 12/15 ft from the bag and way after the BR was there. The PU comes out and calls the runner out for not sliding. A conversation began between the two umps and the PU told the BU if he couldn't handle his calls he should leave. The BU took him up on the offer. This was only one of many bonehead calls I saw this guy make.
