The promotional video shows Amy questioning Penny, "You are actually going to comic-con? and she replies back by inviting her. "Wanna Come?" Penny asks, but Amy is less interested in her offer and explains, "No Thanks, I already live in a place all the nerds come to."

Later we see Penny and Amy in a car as the former says, "I can put up with anything for 3 days!" as Amy points out, "Comic-Con is 5 days" to which she yells out, "Are you kidding me?"

The scene then changes to Sheldon trying to convince his girlfriend to go to Comic-Con. "I am not going with you to Comic-Con!" says Amy firmly, but Sheldon insists, "Maybe what's in my pants will change your mind?", pulls out a piece of paper from his pocket and says, "It's a list of this year's panelists."
