Leonard, Koothrappali and Wolowitz head to the desert to see the Leonids meteor shower. While camping, Wolowitz starts hitting on a few girls, gets nowhere but they give him some cookies to get him away. The guys eat the cookies and soon realize they received an extra ingredient they didn't expect. The guys sit around the campfire, high off their cookies, when Wolowitz reveals how he lost his virginity to his second cousin. Initially this doesn't register with Leonard and Koothrappali in their altered state but this information is not soon forgotten by either. The guys get the munchies and in their feeding frenzy, forget all about the meteor shower.

As Sheldon goes through his pre-driving ritual, Penny tries to keep her cool but he finally manages to get her to the hospital. After the hospital, Sheldon takes her back to her apartment and Penny requests that he now sing her "Soft Kitty". Penny tells Sheldon how much she cares for him and how happy they are friends. He is visibly uncomfortable but appreciates what she is saying.
