However, this is slightly skewed by both Lois and Peter being 18 in " Meet the Quagmires " although only Brian's exclamation that she is 18 supports this.
At the time series creator Seth MacFarlane approached her for a role on the show, she was doing a live stage show in Los Angeles, playing a redhead mother in a sketch.
Several times Lois has forced Peter to have intercourse with her, yet she sees nothing wrong with this as she believes men can not be forced to have sex.
However, she is also a piano teacher on the side to supplement the family income.
She considers herself Protestant but is technically ethnically Jewish, something that both her father-in-law, Francis Griffina devout Roman Catholic, and father, Carter Pewterschmidt bitterly resent.
Once Peter returns to work, he is scolded by his supervisor, Angela, who tells him that his productivity has waned.
Sexual Orientation Although she admitted to only having a bisexual affair in college in " Partial Terms of Endearment ", there have been hints throughout the entire series showing Lois' latent bisexuality even if she does not actively pursue it currently:
Peter's age was later revised to 42 in " Underage Peter ".
Does not appear but is mentioned in " Send in Stewie, Please ".
She has an eponymous song dedicated to her, which was first performed in " Emission Impossible ", on the night that she and Peter attempted to have a fourth child.
