But now Steve Wozniak will try to laugh with the sitcom actors.

The Apple co-founder announced on Facebook this week that he'll appear on an episode of The Big Bang Theory, posting on his social networking wall: 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.

No details on Wozniak's role have been released yet.
