LORELAI: Kevin Bacon, Footloose, reaction to the no dancing in town rule is revealed to him by Chris Penn, brother to Sean, sage to all.
Footloose is a 1984 musical film directed by Herbert Ross, and starring Kevin Bacon as a Chicago teenager who moves to a small town and discovers it has banned dancing and rock music. In the film, his character says, “Jump back!” when his new friend in town, played by Chris Penn, explains to him about the no dancing rule. (Chris Penn, who died in 2006, was a brother of actor Sean Penn, but I don’t know how he was a “sage to all”).
Footloose was the #7 film of 1984. Despite mixed reviews, it is generally held to be cheesy good fun, and has been turned into a stage musical, and had a remake in 2011.
Lorelai jokingly compares her shock at learning that some people get up early, even on Saturday mornings, to the shock Kevin Bacon’s character feels at discovering that an entire town has banned dancing.
