Bad coach/parent stories?

Saw this in another group I'm in and figured I'd share here. Apparently the coach is just straight up bullying the kids (middle school I think) and this dad just got tired of it. I don't know much more of the story than that.

I was thinking about coaching my son's team when he gets old enough but don't think I will now. Not even sure I'll let him play after reading some of the things I have from other parents and coaches.

So let's hear it? What bad coach or parent stories do you have?
