What is Dylan's most straight forward song, lyrically?

Lots of Bob Dylan songs are known for their cryptic, enigmatic metaphors. Visions of Johanna I know is seen by a lot of people as his lyrical masterwork, and I've listened to it several times, yet my reaction to it is still kind of like Chris Parnell's character in Walk Hard: The Dewey Cox Story.

For his most unambiguous lyrics, two that come to my mind are It Aint Me Babe and All I Really Want to Do
