That's nothing.
A friend and I were at Sgt Splatters. Indoor, bunkers everywhere, Attack/Defend style games.

We were defending the house-like structure, and he pops his head out of the window for a few seconds, he ducks back down, and the second he puts his head back up, a paintball nails him in the ear.

Not the side of the ear, IN the ear.
He couldn't hear for a day or two, not properly anyways.

I kind of just died laughing.
