Like a lobster I can swim
And can grow another limb
Where a powerless stump you saw
I have grown a powerful claw
When you'd thought me safely drowned
In the depths I swim around
Dither when you do descend
With my claw I'll tear you, friend [ Lyrics from: http://www.lyricsmode.com/lyrics/f/fairport_convention/the_lobster.html ]
