Lorelai wears a B-52’s (now known as the B-52s) tee-shirt to the parent-teacher night. It’s apparently one she keeps in the car in case of accidents to clothing, and in this case she spilled coffee on herself while driving. The vision of Lorelai sitting half-naked in the car while she changes shirts is a strange one, and we might wonder where and how she managed to do this in a way that nobody noticed.
Perhaps she was able to pull over in the woods on the road to Hartford, or she’s one of those people who think nobody can see them while they’re in a car, despite the windows being made of glass, and happily pick their nose or get undressed in front of others.
The B-52s are an American new wave band formed in 1976, with an original line-up of Fred Schneider, Kate Pierson, Cindy Wilson, Ricky Wilson, and Keith Strickland. They are best known for their 1978 debut single Rock Lobster, and their 1989 hit single Love Shack.
