When a bully picks on Chris, he goes to Peter for help, who ends up beating the kid senseless. Meanwhile, when Stewie goes out without sunscreen and accidentally gets a tan, he becomes obsessed with tanning.
Lois discovers that the school has been teaching Chris incorrect things about sex, so she volunteers to teach the sex-ed class. Meanwhile, Stewie becomes terrified of the tooth fairy and sets traps to catch her.
After blowing off his fingers with some fireworks, Peter can't get all his work done. Lois comes to the brewery to help him out. Meanwhile, Stewie discovers that Brian is dating Jillian, an attractive, but dumb woman.
Brian: You know, Connie, I think I have a theory about why you're such a bitch. Connie: Excuse me? Meg: Brian, let's just go. Brian: No, no, no, no, no. Now hang on... hang on, Meg, hang on. You see, Connie, you're popular because you developed early and started putting out when you were 12. But now you can't stand to look at yourself in the mirror because all you see is a whore. So, you pick on Meg to avoid the inevitable realization that once your body's used up by age 19, you're going to be a worn-out, chalky-skinned burlap sack that even your step-dad won't want. How's that? Am I in the ballpark? (Connie cries and runs)
