Doctor Harvey J, and Fireman Ollie, have been busy measuring everything in their N London garden.
They've measured slugs, trees, each other, and countless other things.
Some children play with hand-held, battery-operated, killing games. Some climb trees and swim in ponds. But this devilish duo find fun in taking out the old tape measure and simply 'measuring'.
I've got a great idea for their Christmas (sorry about that) presents!!
