This. Either you get it or you don’t. There’s no particular cosmic secret to it or anything. It’s a just a joke. You’re either in the spirit of it or you’re not. Bob Dylan is divisive like that, and this one of his most intensely love-it-or-hate-it moments. I can definitely understand that if you don’t happen to be a fan of incomprehensible lyrics or people who sing like drunk frogs, Dylan can be excruciatingly annoying. Which also happens to make him appealing to people who enjoy the knowledge that the things they’re into are annoying to others. That may be part of the reason why, in his heyday, his followers dubbed him the voice of his generation. Because the young generation really made it a point to confuse and irritate their elders; it feels so revolutionary and radical when the things you enjoy are closed off to outsiders who just don’t get it, man. But that’s just a common trait of being young and eager to break the apron strings. That’s why there’s been so many annoying subcultures based on annoying things. Bob Dylan, for his part, found the phenomenon of being the voice of anyone but himself extremely annoying, and spent a great deal of time and energy trying to alienate his own fanbase. He didn’t mean for his funny joke song to represent the enmity of generational groups and the cultural disjointment caused by radically changing values. It just happened to.
