Yoda lives, and he's a japanese missile scientist. I have been proofreading for a professor from the local university who is actually a leading japanese expert in missile defense theory. He's really just Yoda in disguise though.
Get this, he's short, even by japanese standards, he has an unkempt mop of grey hair, he has brownish-greenish teeth from all the coffee and whatnot that he drinks and the clincher is that he makes the same throat noise that Yoda does, constantly. Who better to calculate "Force Vectors in Anti-Missile-Missle Countermeasures" than a Jedi Master? Believe me if I ever want to know about the Force, I'll go straight to Yoda.
