The Fat Controller, Thomas and others in “Thomas Comes to Breakfast”

[firmly] You are a very naughty engine.

[with guilt] I know, Sir. I'm sorry, Sir.

Thomas' voice was muffled behind his bush.

[calmly] You must go to the works and have your front mended. It will be a long job.

Yes, Sir.

Meanwhile, a diesel rail car will do your work.

A-A-A d-diesel, Sir?

Yes, Thomas. Diesels always stay in their sheds till they are wanted. Diesels never gallivant off to breakfast in stationmasters' houses.
