-You imprudent scallywags! -Whatever are young engines coming to nowadays?!-Well you better mind, unless you want to end up like Smudger. Smudger, was a showoff.He rode roughly, and would often come off the rails. I warned him to be careful, but he took no notice.-We do here, I said, but Smudger just laughed. Until one day, manager said he was gonna make him useful at last. Smudger stopped lauging then.-He turned him into a generator. He's still out there behind our shed. He'll never move again.

Keep me in order?! Be off with you! Imprudent scallywags!.
