'Big Bang Theory' Brings Stephen Hawking on as Guest Host

"The Big Bang Theory" is getting a visit from Stephen Hawking.

The renowned theoretical physicist will guest-star on the April 5 episode of the CBS comedy, the network said Monday. In the cameo, Hawking visits uber-geek Sheldon Cooper (Jim Parsons) at work "to share his beautiful mind with his most ardent admirer," according to CBS.

Executive producer Bill Prady said that having Hawking on the show had long been a goal, though it seemed unattainable.

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,” Prady said. “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.”

Hawking, known for his book "A Brief History of Time," has appeared on television comedies before, albeit in voice work. Hawking has done a guest spot on "Futurama" and appeared as himself on several episodes of "The Simpsons."
