Get ready to cringe, fellas. From the Cubs official site,
...outfielder Felix Pie missed a couple of days early because of a twisted testicle.Ouch.
I've no idea how it happened, and I'm not sure I want to know. Maybe he sneezed a la Sammy Sosa. Maybe Carlos Zambrano got angry at him, and thought he needed to learn a painful lesson. Who knows?
The only thing I do know, is that there aren't many other things I can think of that are more painful than a twisted testicle. Mine start to hurt just typing it. Kudos to Felix for only missing a few days. If that happened to me, I'd probably need a week or two off.
