Parental rage at kid sporting events

I've coached soccer for several years, but I'm relieved that I never had one of the parents as bad as this one:

Here's your Little League Dad of the Moment. First he cusses out his own kid during the game just to grind down his son's self-esteem a bit, then he lets his anger at the coach boil in his chestal area for two days, after which he threatens the coach outside his home. According to charges, he phoned up the coach and said he'd shoot him "like a dog." Brilliant.

This story serves several important purposes:

1. Every year must have a crazed-sports-father case. This is the one for 2007. We keep waiting for a dad from a different sport, like curling, but it's always Little League, soccer, or hockey. Never interpretative dance. Never have a parent stand up and shout I'M NOT GETTING THE IMPRESSION OF A WOUNDED FAUN, YOU #*&*%(#$ LOSER! INTERPRET HARDER! HUSTLE! HUSTLE! No, it's always the popular sports that attract the guys with M-80 tempers

The worst case I encountered was with two mothers who hated one another so much that their kids weren't allowed to be on the field at the same time (the kids weren't the problem, it was definitely the mothers who had the issues). When I pointed out that I couldn't do that — there weren't enough players to allow me to orchestrate my rotation around their personal issues, one of the mothers pulled her kid from the team.
