Melissa Rauch who also plays Summer from 'True Blood' surprises fans at Comic Con 2013 by showing up as a moderator.

Rauch began the show by asking fans the questions that they had for the writers. One fan answered the call, dressed covered head to toe with a Boushh bounty hunter costume from 'Return of the Jedi,' came forward to the microphone and asked a daring question about why the writers think Johnny Galecki's hard to work with.

In her cute rage of anger, she asked the fan, "Who are you?"

"Someone who loves you!" he responded and immediately removed his helmet to show himself as Johnny Galecki. Galecki then went over to the seats to join the writers.

The writers revealed that Raj (Kunal Nayyer), who had a crush on Bernadette (Melissa Rauch) some time ago, will finally be able to talk to women while sober.

When Melissa Rauch was asked if Amy and Sheldon will be taking the next step, Molaro commented saying: "Once you erotically massage someone's nose I think we all know what happens."

"This who has the best fans in the world," Galecki said to wrap up the Melissa Rauch-moderated event, "The fact that we gather here in July before the show goes back into full swing production in August gives us the shot in the arm we need."
