YMMV / Thomas And Friends S 3 E 20 Tender Engines

• Memetic Mutation: "Educating Gordon Day" become adopted by fans as being June 2, 1992, the original UK air date of the episode.
• Nausea Fuel: Boiler sludge. The engines find it vulgar to talk about. Those who have seen the stuff in real life know why; it's that stuff that builds up in the tubes of boilers. In-Universe, it is apparently the locomotive equivalent of human waste.
