Cockiest Quote: "My I.Q. is 188. End of discussion, it's been proven. Certified genius."

Brian Wilson is as big a celebrity as there is in baseball, especially impressive when you consider that he's a reliever on the not-so-hyped San Francisco Giants. He's made a spectacle of himself with media appearances, an overgrown beard, and showed up to the ESPY's in a spandex tuxedo. Wilson recently described his ominous goal as a closer is to "murder souls." Yikes.
