Barenaked Ladies, Wil Wheaton add 'Bang' to Comic-Con

Bazinga!

The Barenaked Ladies kicked off a fun-filled panel for "The Big Bang Theory," inviting enthusiastic audience members to join in on a performance of the comedy's theme. There is "nothing nerdier than a sing-along," moderator and "Big Bang" guest star Wil Wheaton teased the crowd.

With CBS moving the ratings juggernaut to Thursdays at 8 for Season 4, pitting it against NBC's "Community," it didn't seem like the panelists were worried about a possible drop-off in viewership. Instead, there was a lot of geek talk, a "Soft Kitty" and gentle ribbing between the moderator, cast members and co-creators.

"Is it geeky that I cried during an accordion solo?," Simon Helberg asked, after the Barenaked Ladies finished the "shared nerd experience."

"I'm geeky for talk radio," Emmy-nominated actor Jim Parsons said. "I like to hear people talking and answering and asking questions, I find it comforting. That's probably not geeky, that's probably a cry for therapy."

As the anchor of the show, Johnny Galecki identified with his character Leonard. "I knew immediately there was a frustration there that I could relate to," he said. "It's that angst-filled 'grass is greener on the other side' that I'm definitely guilty of in my life."

Co-creator Chuck Lorre added his two cents: "He's the only character whose trying to reach outside of himself, so he suffers."

"Leonard and Sheldon both have the mothers that the other would've wanted," Galecki said during the serious portion of the session.

When Wheaton asked Parsons his last question, the actor wasted no time. "Yes, I enjoyed working with you," he answered quickly to the crowd's amusement.

Of course, Comic-Con wouldn't be productive without minor spoilers. Lorre spilled that Steve Wozniak would be guest starring in the new season. Mayim Blalik, who was featured in the Season 3 finale as a possible love interest for the asexual Sheldon is also returning.

During the fan Q&A portion, a young girl asked the cast who their best friend was in the cast, which prompted the panelists to go in a mild downward spiral. "See, she wants to break this cast up! ... There's Wil's evil daughter!," Kaley Cuoco joked.

"I'll tell you who's the most talented," Parsons said with a laugh. "That is awful. You're a horrible little girl. Where are your manners?"

When another fan asked the cast if they had a favorite line, Kunal Nayyar had a suggestion for Parsons: "Jim, do rock-paper-scissors-lizard-spock."

"I didn't hear what you said and I'm OK with that ...," Parsons replied in his offbeat way.
