<P> Evidence of Penny's affection for Sheldon is apparent in various episodes . Penny takes care of Sheldon while he is ill and lets him stay at her apartment when he is locked out of his, or if he has a bad dream or is feeling unsafe; Sheldon lent her money when she needed it and takes care of her when she dislocates her shoulder . Despite not being as well versed as the men in geek culture, Penny has shown attention to what each of her friends likes, although she still remains dismissive of them: during a Christmas episode, Penny gives Sheldon a signed napkin autographed by Leonard Nimoy . In return, Sheldon gives Penny several baskets of bath products and then a long hug, to both her and Leonard's surprise . When Sheldon's World of Warcraft account is hacked and the four men all back down from the much larger hacker who also steals Sheldon's Klingon Bat'leth, Penny kicks the hacker in the groin . Following her breakup with Leonard, Penny takes Sheldon along when she and some friends from work went to Disneyland, for which he is thankful . In the same episode, "The Spaghetti Catalyst", she notes that she takes Sheldon shopping for his linens . (This episode also shows her and Leonard acting like a divorced couple and Sheldon is their "son", a dynamic that recurs in successive seasons). She has also helped Sheldon resolve conflicts with Amy, as in "The Shiny Trinket Maneuver". </P> <P> In "The Panty Pinata Polarization" Penny has a fight with Sheldon as he banishes her from his apartment and using their Wi - Fi as she got "three strikes". She defends herself by refusing to take down his order at the restaurant and then ruins his weekly Saturday laundry night but then he puts Penny's underwear on the telephone wire . After having a heated argument with his mother, Sheldon apologises to Penny and then they make amends with one another . </P> <P> Sheldon has also acknowledged that he likes Penny, although he claims this was only because he was forced to because Leonard "made him", and that Sheldon liking her was a "hard row to hoe", although in "The Intimacy Acceleration" Sheldon has admitted that he considers Penny a sisterly or motherly figure . </P> <P> A number of episodes depict Penny's assimilation of nerd culture through her relationship with the men, and has developed to quote some science fiction shows (like Star Trek), and movies (Star Wars). After Sheldon introduces her to the online role - playing game Age of Conan, Penny becomes addicted, to the point of ignoring her friends, her hygiene, her general appearance and her job, and pesters Sheldon incessantly for gaming advice . She finally overcomes her addiction when she realizes she has agreed to go on a virtual date within the game with Howard . </P>
