“When people would ask us who a ‘dream guest star’ for the show would be, we would always joke and say Stephen Hawking -- knowing that it was a long shot of astronomical proportions,” executive producer Bill Prady said in a statement about the show. “In fact, we’re not exactly sure how we got him. It’s the kind of mystery that could only be understood by, say, a Stephen Hawking."
For the uninitiated, the show is about four nerdy friends -- Sheldon, Leonard, Howard and Rajesh -- who all have impressive jobs and degrees in science. They play video games, collect comic memorabilia, discuss complex scientific topics and socialize with Sheldon and Leonard's neighbor, Penny. This won't be the first real-life techie guest: In 2010 Apple's Steve Wozniak had a cameo on the show. He interacted with a virtual Sheldon: watch here.
