Sports: Appropriate Names

Atlanta Braves outfielder Ryan Langerhans. "Langer" is Irish slang for an idiot (or the male member), and "hans" sounds like "hands" - so he's Ryan Idiot-Hands.

The Islets of Langerhans are cells in the pancreas, named after the German scientist Paul Langerhans.

What's that other body part (something in the ear?) that sounds like a geographical feature?

The Braves also have a third baseman called Wilson Betemit, which may or may not be pronounced like "Better Mitt".
