It has been announced that the second man to walk on the moon, Buzz Aldrin, is set to make a cameo appearance on The Big Bang Theory.
The 82-year-old astronaut will appear in an episode of the CBS sit-com, which can be seen on TV screens here on RTÉ Two, called The Holographic Excitation, reports TVLine. The episode will be seen in the US in the next few weeks.
The gang get together for a Halloween party at Stuart’s comic book-store, where they also first met up with occasional guest star, Wil Wheaton from Star Trek: The Next Generation.
Aldrin is not new to TV cameos, having already appeared in 30 Rock, Futurama and Numb3rs. Other guests on the show include physicist Stephen Hawking and the voice of Leonard Nimoy.
