Target: Eric Schmidt

Shot fired: "Fucking Eric Schmidt is a fucking pussy. I'm going to fucking bury that guy, I have done it before, and I will do it again. I'm going to fucking kill Google."—Steve Ballmer

No one in the biz has a hotter temper (or foul mouth) than Ballmer. According to a report from Vanity Fair, dude spazzed and hurled a chair at an engineer leaving for Google, while implying CEO Eric Schmidt was soft.  We'd love to hear what he might have called Steve Jobs upon hearing the news of an employee joining Apple.
