The famous computer engineer updated his Facebook status saying: "What's it like to film an episode of Big Bang Theory? I'll let you know tonight, but not what the episode is about."
He would be a good match for the show in many ways. It's about a tight-knit group of nerds who are obsessed with video games, science fiction, science and, yes, computers. That said, they're generally Windows user/PC gamer types, and we can imagine that if the show's obsessive-compulsive, socially inept Sheldon Cooper character comes in contact with Woz he'll have quite a few critical quips about Apple culture.
Wozniak's no stranger to television. He has previously appeared on Dancing With the Stars, and he dated talk show host and comedienne Kathy Griffin, appearing on her program occasionally.
Although this is Wozniak's first appearance on the show, The Big Bang Theory has hosted geek cameos before; Twitter celeb and Star Trek alum Wil Wheaton is a recurring villain on the show.
