Thanks y'all. My wife isn't familiar with it it either, and doesn't find it funny. I'm around 20-somethings a bit, and it's fairly common. No, Don't think twice doesn't use it, of course, or any of the other tunes, and the joke is in the incongruity and mangled phrasing, especially by an old white guy like me who can't get it right. Also thought of Billy Joel's Piano Man "we're all in the mood for a melody, and you've got us feeling a'ight. He's a better victim of this joke than Dylan, especially for a horrible faux-rap thing he did once.

Rather like substituting "dude" for Dylan's fondness for "babe" or simply adding a few more --i.e. It aint me, babe, that you, babe, are looking for. Babe.

And a bit like Martin Mull's white blues Woke up this mornin' and both my cars were gone, felt so low down deep inside, I threw my drink across the lawn.

I think I better be careful to do this joke around those who are familiar with it. thanks again.
