It aired yesterday, and it was the best episode of The Simpsons in years. Lisa becomes the manager of Bart's little league team, and learns Sabermetrics from the local nerds. The episode includes lots of "stats geek" jokes, a cameo by Bill James, and, in a callback to the original baseball episode, an appearance by Mike Scioscia. My years of dedication to the show have finally paid off.
