In S1E14, Rory agrees to watch Babette and Morey’s new kitten for the evening. Lorelai teases Rory about being so eager to get away from her for the night. She tells Rory, “Well, Paul and Linda McCartney only spent 11 nights apart their entire relationship. Did you know that?”
Paul McCartney, bassist and songwriter for the Beatles, married Linda McCartney, photographer and animal rights activist, in 1969. They stayed together until Linda passed away in 1998 from breast cancer. General consensus seems to be that the only nights the couple ever spent apart were the 10 days that Paul was in jail in Japan for marijuana possession.
