Barbie blackbird

At some point in its life, our blackbird has been heinously exposed to "I'm a Barbie girl" on the radio or playing from a child's window.  In amongst his repertoire of chirps, warbles and whistles, repeatedly he sings the first line of that song ... which inevitably has left me with an extremely annoying ear-worm and a reflex action to follow with "In a Barbie world".  Farmer Ian is being stoic, but that may not last much longer...
