A cost cutter…

The National Grid

Cutting himself off from the national grid
Was almost the very last thing that he did.
With a saw, a drill and a pair of pliers
He managed to hew his way through the wires.
The jolt he received was a helluva shock
Which sent him hurtling round the block.
Should you too decide to have a go
Be ready, dear friend, for the afterglow.
