“If eating cake is wrong, I don’t want to be right”

RORY: Is it right to be sampling wedding cakes when Sookie’s making ours for free?
LORELAI: What is right anyway, you know? Who defines right? And if eating cake is wrong, I don’t want to be right. … So, ethics?
RORY: Highly subjective and completely overrated.
LORELAI: That’s my girl.

Lorelai refers to the 1972 song “(If Loving You Is Wrong) I Don’t Want to Be Right”, written by Homer Banks, Carl Hampton, and Raymond Jackson. Originally written for The Emotions, it has been performed by several singers, most notably Luther Ingram, whose original recording from his album of the same name went to #3 in the US, and #1 on the R&B charts. It was the #16 song of 1972.

Lorelai and Rory decide that committing fraud to rip off a little old lady is alright because they are Gilmores and therefore special. Note that Rory, “the sweetest kid in the world”, is perfectly okay with this, and has already scarfed down a large amount of cake before even raising the question of whether it might possibly be wrong.
