  Stephen Hawking, that smart and handsome man, was urlLink in the news recently. It got me to thinking about his appearance on urlLink The Simpsons . Since Prof. Hawking has no voice, did they wheel him into the studio and put a mic next to his voice synthesizer, or did they run his lines through any old synthesizer and just get permission to use his name and likeness? That's far more profound than information escaping a black hole over aeons.
