Screws

Five, four, three, two, one

A little screw went for a run

And now without this little part

Everything just falls apart

If you think a screw is nothin\'

Take \'it out but just beware

Everything will break without \'em

With no little screws in there

The bulldozer was a strong one

Until there was a thud

And then the mighty giant

Fell straight into the mud

The mighty crane was working

Until there was a pop

And then the mighty giant

Gave out and lost its top.
