Stephen Hawking

Has Dr. Sheldon Cooper met his match?

The Big Bang Theory has finally nabbed famed theoretical physicist Stephen Hawking to film a cameo.

As first reported by TV Guide Canada, Hawking filmed a scene with Jim Parsons, a.k.a. Sheldon, Friday for the show's April 5 episode. In the scene, Hawking has a "run-in" with Sheldon.

Leonard Nimoy becomes Big Bang Theory's "dream" guest star

The CBS comedy had invited Hawking to appear on the show before, but at the time they were told he was too ill to participate. Hawking's appearance will air the week after another big guest star stops by. Star Trek's Leonard Nimoy will lend his voice to the March 29 episode when he speaks to Sheldon in a dream sequence.

Hawking, coincidentally, played a hologram of himself on an episode of Star Trek: The Next Generation, and also played himself on The Simpsons and Futurama.

Are you excited to see Hawking and Sheldon together?

The Big Bang Theory airs Thursdays at 8/7c on CBS.
