The Big Bang Theory's good luck with guest stars just keeps coming. The show recently landed Leonard Nimoy, and now it's been announced that superstar physicist Stephen Hawking will make an appearance in an upcoming episode.
Hawking, 70, will reportedly have "a run-in" with Sheldon Cooper, who has a reputation for angering well-known scientists. He's previously annoyed astrophysicist George Smoot and theoretical physicist Brian Greene.
The Big Bang Theory has apparently sought after Hawking as a guest for some time, but the professor, who suffers from motor neurone disease, wasn't feeling well enough to appear until recently.
Executive Producer Bill Prady recently tweeted about a "super-secret, super-cool guest star for episode 521." If he was referring to Hawking, that means we can expect the physicist's cameo to air on Thursday, March 29th.
