Tom Waits has a wonderful tune called "Shiver Me Timbers":

And nobody knows me
I can't fathom my stayin'
Shiver me timbers
I'm a-sailin' away


i remember Popeye saying this phrase, along with Blow Me Down. i take "blow me down" to be akin to "you could knock me down with a feather", but whence comes "shiver me timbers"??
