Jason: Why not Duke's?
Lorelai: It's not so special.
Jason: You go there daily.
Lorelai: Yeah, but I think Duke's is closed and it's Luke's.
Jason: Closed at eight in the morning on a Friday?
Lorelai: Yeah. Sabbath.
Jason: Duke's a Jew?
Lorelai: No, Luke's a Jew.
Jason: Sabbath's not 'til sundown.
Lorelai: Well, he likes to get an early jump on his... Sabbathing.
