(Penny is asking Leonard to get her 13-year old nephew some comic books for his birthday).
Penny: Could you pick me up a few comics for my nephew's birthday?
Leonard: Sure. What does he like?
Penny: I don't know, he's 13. Just pick out anything.
Sheldon: Just pick out anything? Maybe at the same time we can pick out a new suit for him without knowing his size, or pick out his career for him without knowing his aptitude, or pick out a new breakfast cereal without knowing his fiber requirements or his feelings about little marshmallows.
Penny: Spider-Man. Get him Spider-Man.
Sheldon: Amazing Spider-Man, Ultimate Spider-Man, Spectacular Spider-Man, The Marvelous Adventures of Spider-Man, Spider-Man 2099? .. Oh, I forgot Sensational Spider-Man.
