Has anyone noticed that the riff is from The Joker from The Steve Miller Band!
And the words are from another song too!
Here's the guitar line

There you go.  It sounds like a bass plays this most of the song,
but if you listen you can here an acoustic playing in on the chorus
and a little in the verse.
