Remember Footloose? Of course you do. The '80s flick may be 30 years old, but new generations discover it all the time thanks to cable reruns, and, of course, YouTube. While The Following may have formally submitted the 1984 film's central dance hero, Kevin Bacon, into the Serious TV Actor's Club (McConaughey presiding), he sure hasn't lost his groove. All it took was new Tonight Show host/gonzo music enthusiast Jimmy Fallon to prove it. And how do you coax Bacon to dance? You tell him it's illegal, of course.
