Eh.. it's not too bad. A scratch here and there, and the odd glasses flying off. It's way more fun than it is dangerous :)
No, dodgeball is no fun at all when the stakes are higher and you aren't yet well coordinated (this was high school; for some reason, I didn't get coordinated until my college years, perhaps when I stopped growing...).
There's also the minor detail of it being involuntary. I should have told the coaches to f--- off and that I'd get a GED when the time came to graduate....
