LOS ANGELES, March 13 (UPI) -- British theoretical physicist and cosmologist Stephen Hawking is to guest star on the U.S. sitcom "The Big Bang Theory," CBS said Tuesday.
"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. "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."
