Funny, but very, very true. I work as a little league/ high school ump here in N. Texas. I won't tell you what city, because I know that some people on this board probably have kids in this age group, but this is a true story of what we go through.
First off, in my 7+ years of umping, the "worst" parents are the parents of the 6 to 10 year olds. Which is why I won't ump for that age group. The coaches aren't much better. Most parents believe their kid is the next A-Rod, and most of the parents (and coaches) don't know a flip about the rules.
In fact, in our pre game meeting with the coaches, we will tell them that contrary to what they think, they aren't Joe Torre, they aren't coaching a team to the W.S. and most likely, none of their players will ever make it to the bigs. It didn't go over well with the coaches at first. Somewhere, just playing for the "fun" of it was lost.
