Okay, what the fuck. That's ridiculous. I'm no fan of using metal bats in baseball on any level, but a warning? On a BASEBALL BAT? FUCK THAT SHIT.
Sure, metal bats make balls go faster, but you could still die after being hit with a ball off of a wooden bat. It's just common knowledge that 1) metal bats are stronger and 2) if you get hit in the head with a baseball after it is hit very hard, you'll get fucked up.
