"21st Century Man"

When I listened to Time yester-day, I also noticed the structure of this verse in "21st Century Man":

Things ain't how you thought they were

Nothing have you planned

So pick up your penny and your suitcase

You're not a 21st century man

The syntax of the second line is inverted, apparently so that "planned" will come at the end of the line in order to rhyme with "man," but this inversion also illustrates the line "Things ain't how you thought they were."  Instead of a normal word order ("you have planned nothing"), there's this unexpected inversion.
