LORELAI (to Rory): Oh you’re going to have a great time. The Bangles are the best! They were my favorite band in high school. I almost named you Susanna.
We find out here that not only was The Bangles Lorelai’s favourite band as a teenager, but she almost named Rory after Susanna Hoffs (born 1959), their lead singer. Susanna’s middle name is Lee, very similar to Rory’s middle name of Leigh.
