LUKE: There wasn’t really that much for her to eat on the menu, so I just . . .
LORELAI: Oh, you added three more salads just for Nicole. When I asked you to add chili-topped Pringles, you said no.
Pringles, brand of stackable potato-based chips made from fried dough invented by Procter & Gamble in 1968 and marketed as “Pringle’s Newfangled Potato Chips”. The brand was sold in 2012 to Kellogg’s.
