Luke: Why do you want me to fire Brennon?
Lorelai: Come back, little spark, come back.
Luke: Lorelai.
Lorelai: He doesn't write the orders down, he never brings you food that's hot or yours, he can't distinguish bagels from doughnuts, he hands out butt napkins, and he has worn that Foreigner t-shirt every single day since he started working here and he doesn't know who they are. I asked him.
Luke: What are butt napkins?
Lorelai: Kirk needed a napkin, and he pulled one out of his back pocket.
