You have to see this one!

The most important things we can learn from this is, whatever level you are working as an umpire,..
a) learn , know and discuss the ground rules of the facility you are working before the game.
b) before the game, make a thorough walk around of the field to see if there is anything beyond the fence (poles, trees, signage etc) which can fool you into making an improper call.
