Built off three phrases which all refer to the delights of employment:
This is me talking to myself ( again- oh dear)
Walking through treacle with lead weights around your neck:
Trying to wake up when you're in the middle of a nightmare;
Climbing up a ladder with a pack on your back;
That just about sums it up ( the teaching I love but the stuff I have to do to make the money - not so good )
The style is taken from Colin Hays( from Australian band Men at Work) cameo appearances playing in a cupboard in the US sitcom Scrubs - which our lot loved.
