2nd year in high school, a Riddel salesman came to try sell the coach on new helmets. I was "volunteered" to offer a hand ... quite literally.
Guy had me put my hand palm down on a desk and proceeded to remove the padding .. Actually liquid padding, I think...from the helmet and placed the pad over my hand.
He then wound up the helmet by the facemask and whacked it on my padded hand. Didn't feel anything but the thrust of the helmet.
Coach said, "Ok, but that guy played last year with a broken bone in his foot and played the very day he had a wisdom tooth removed."
Salesman asked, "Coach, you saying he's too dumb to know he's hurt?"
I just replied, "I'm a middle linebacker."
Salesman said, "Oh"
Whatever that meant.
