Since The Big Bang Theory panel was only supposed to include the writers and producers nobody expected any cast members to show up at the Ballroom 20 event yesterday morning. Fans were treated to a few unexpected surprises when actress Melissa Rauch, who plays Bernadette on the series, was revealed as the panel moderator. And then, what will likely be a highlight of this year's Con, a "fan" dressed in a Star Wars costume who approached the mic to ask a question turned out to be none other than Johnny Galecki. We have the full Comic-Con 2013 panel for The Big Bang Theory, where you can see all the hilarity unfold before your very eyes, and you didn't even have to go to San Diego to see it!

We reported last month that the Season 7 Premiere will debut on Thursday, September 26 at 8 PM ET on CBS.
