"The Big Bang Theory" -- the unofficial Comic-Con sitcom due to its relentless spoofing of all things geeky -- is about to get prime exposure as CBS' 8 p.m. lead-off show on Thursday nights this fall. But it apparently won't drop its connection to the nerd universe: Apple co-founder Steve Wozniak has been tapped for a Season 4 guest spot, it was announced at a Comic-Con panel Friday.

Unlike Steve Jobs, Wozniak, Apple's "Other Steve," has become a regular on the entertainment circuit. He was a contestant on Season 8 of "Dancing With the Stars" and frequently showed up on "My Life on the D-List" (at the time, he was dating star Kathy Griffin).

For stunt casting, "The Big Bang Theory" often turns to celebrities beloved by the geek community, with people such as Wil Wheaton (the fanboy actor and blogger) and Nobel laureate George Smoot appearing in walk-ons or semi-regular parts.

The Comic-Con panel also revealed that former "Blossom" star Mayim Bialik will return in Season 4 as the love interest of Sheldon (Jim Parsons).

One questioner from the crowd at Comic-Con -- warmed up with a live performance of the theme song from Barenaked Ladies -- suggested that the show is such a natural for the convention, the producers should film an episode there. Cheers erupted throughout Ballroom 20 at the San Diego Convention Center.

But co-creators Chuck Lorre and Bill Prady shot down the idea. "We're an indoor cat," Lorre said.
