Apparently, a double standard also exists against Meg, further underscoring the mistreatment she suffers from the people around her. In "Big Man on Hippocampus", an episode wherein Peter loses his memory, as he reacquaints himself with the pleasures of sex, Lois tells him that it is inappropriate to have sex with his own children; in response, Meg attempts an incest joke. She then lambastes her for this and kicks her out of the room. However, in the season finale "Partial Terms of Endearment", Lois tells a joke that implies that it was Meg that gave birth to Stewie, and apart from a shocked reaction from the latter, Lois receives no such violent reaction. Additionally, in "Model Misbehavior", when Lois starts a modeling career, Peter states that he will pleasure himself to Lois' pictures, followed by Chris and Meg both exclaiming "Me too!" to which Peter shouts "Oh God, Meg, that's sick! That's your mother!", ignoring the fact that Chris said the same thing first. Meg responded by saying "I was only trying to fit in!" Peter immediately kicked her out of the house. Later, during an unrelated conversation, when she tried to insight Peter on how Lois' behavior from modeling made a poor example for women, he said "Meg, who let you back in the house?"
