LORELAI: And I said something at the table about the pâté smelling like Clorox and one thing led to another and I wound up here. I hadn’t told anybody yet about me. And you.
Clorox is an American brand of household cleaning bleach, made by the Clorox Company, founded in 1913.
The pate would have smelled unpalatably bleach-y to Lorelai because she was pregnant; pregnancy can change the way you perceive odours and flavours. As Emily and Richard didn’t know she was pregnant, they probably thought Lorelai was being a rude brat, and sent her upstairs. Could this help explain Lorelai’s disdain for pâté?
