LORELAI: You’re going to quote Freud to me? ‘Cause I’ll push you in front of a moving car.
After Luke says it’s not surprising that Rory is attracted to a boy who reminds Lorelai of Rory’s dad Christopher, she believes he might be thinking of Freud.
Sigmund Freud (1856-1939) was an Austrian neurologist and the founder of psychoanalysis. The Oedipus complex – named after the play Oedipus Rex by Sophocles – was a theory he coined in 1910, to describe a child’s unconscious sexual desire for their opposite-sex parent. Some modern psychologists broadly agree with his theory, while others find no evidence it exists. Studies apparently suggest that we are more likely to seek partners with vague physical similarity to our parents.
Luke says that he just meant that Lorelai and Rory are quite alike in their tastes, and it shouldn’t come as a surprise they would be attracted to similar men.
