In S1E10, Luke watches Lorelai come up with excuse after excuse not to see her father, who is in the hospital. Once Rory and Emily go in to see Richard, Lorelai struggles to think of a reason to stay outside. Luke says, “So who are you gonna go find now? How about Jimmy Hoffa? That’ll keep you busy for a while.”
Jimmy Hoffa was an activist and president of the International Brotherhood of Teamsters union who disappeared in 1975. Hoffa was supposed to meet with two mafia leaders in a restaurant parking lot, but they never showed up. Hoffa was seen driving away from the meeting location with another man. Investigations did not reveal Hoffa’s fate, but he was legally declared dead in 1982.
