Quote from Rachel in The One with the Truth About London
Ross: I don't want you teaching my son that stuff anymore. Okay? Rachel: Fine. Fine. But I'll have you know, once I taught him that stuff, he called me "fun Aunt Rachel." And I loved being fun Aunt Rachel. Ross: I'm glad you guys were bonding but- Rachel: Look, he doesn't have any brothers or sisters. Somebody's going to have to teach him this stuff. And I haven't taught him anything that a normal 6-year-old doesn't know. Ben: [o.s.] Crap! Rachel: I gotta go.
