The Big Bang Theory Episode 6.13 The Bakersfield Expedition

The guys decide to go to the Bakersfield ComicCon, but on the way, they opt to stop for some photos at the Vasquez Rocks, which is where many of the most famous episodes of Star Trek were filmed. Once there, they get distracted taking photos in their Star Trek costumes and someone steals their car, along with all their cell phones and everything inside it. They are forced to walk to the nearest diner, where they can call the police and a ride home. On the walk, they discuss the fact that they're all grown men now, and that it might be time to move past their fixation on comic books and fantasy lore. Meanwhile, Penny, Amy, and Bernadette discuss their boyfriends' fixation on comic books over dinner, and they decide that they should read one to see what all the fuss is about. They go to see Stuart at the comic book store, who is absolutely stunned to have women in his shop, and they eventually decide to read a comic about Thor because "he's hot." After reading it, the girls decide they don't like it, but wind up getting in an argument over Thor's hammer. To solve it, they start researching other comic book lore and wind up getting sucked into the fantasy world their boyfriend's love so dearly. The guys arrive back home from their excursion, set on moving on from comic books, only to find their girlfriends in the midst of a heated comic book argument that they can't possibly stay out of.
