Have you ever had Parents...

[Andy]

My experience at this age group has been that alot of "problem" coaches are coaching for the first time and the only "role models" they have are what they see on TV. They think that their job is to try to influence the umpire as opposed to teaching and coaching the players.

JEL gave you some excellent advice on how to handle these idiots - warn 'em then dump 'em!

Much the same goes for the parents, the only way they know how to behave is exactly how they behave or see fans behave at the big league games. Not much you can do but laugh at 'em and ignore them. Another line I liked to use if one of these parents approached me after the game complaining:

Wow, you seem to know an awful lot about the game, can I get your name and number to provide to my UIC? We are very short of umpires in this area and would love to have you come out and show everybody how good you are! (Say with dripping sarcasm)
