Wearing a glove to a baseball game is kinda overambitious, but if you're at the Home Run Derby, where the express goal is to hit balls into the crowd, you ought to come prepared. Forget your mitt when, say, Giancarlo Stanton blasts one over the wall, and you might end up like this:
And then Giancarlo uses you to make questionable puns (and maybe send you his glove?)
That is a pun, right? Bear like barehanded? Or does he have big hands like a bear or something? I'm so thrown off by the pun that I don't even care about that badly bruised hand anymore.
