Quote from Norm in Strange Bedfellows, Part 3
Cliff: Oh, trouble in paradise, Norm? Norm: No, at home, Cliffie. I just put Vera on the train to Springfield. I have to spend the next few days at home alone with her oversexed, exhibitionist sister, Donna. Steve: You know, maybe she's an innocent kid, and you misinterpret her friendliness. Norm: Maybe you're right. You tell me, is it normal for a girl to get dressed on the front lawn?
