Grandchildren: Come on, Grandfather! Do look at this engine. The Fat Controller: That's a tram engine, Stephen. Bridget: Is it electric? Toby: [angrily] WHOOSH!! Stephen: Shh! You've offended him! Bridget: But trams are electric, aren't they? The Fat Controller: They are mostly, but this is a steam tram. Stephen and Bridget: May we go in it, Grandfather? Please? The Fat Controller: [to the guard] STOP!
