For those who haven't figured out Ron Washington's body language, after the jump, I offer a couple of gifs that will illustrate for you the subtle difference between happy Ron Washington and angry Ron Washington...
Here is angry Ron Washington, arguing a call that went against the Rangers in Seattle:
Notice the double-fist-pumps, with the hands low.
Now, here is happy Ron Washington, celebrating Josh Hamilton's walk-off single last night:
Single fist pump, with the hand high.
