R.A. Dickey is a pitcher on the National League All-Star team, and his calling card is throwing a ton of knuckleballs. You've probably heard about that, although if you haven't, wow, I bet your mind just got blown. Knuckleballs are super difficult for catchers to catch, and R.A. Dickey's catcher isn't a National League All-Star, so Dickey brought along his own catcher's glove for All-Star catcher Carlos Ruiz to use when he's catching him today.

A glove comparison:

The glove on the left side of the photo is a normal catcher's glove, constructed in the normal way from the normal source. The glove on the right side of the photo consists of 98 percent of the skin of a mammoth scientifically bred and nurtured for the very purpose of being slaughtered upon adulthood and turned into a baseball glove to catch knuckleballs.
