I used to have muffins for breakfast in London with a fried egg.

As for crumpets, they're what the English call pancakes, not to be confused with pancakes, which the English call drop scones, or French pancakes, which the Bretons call krampouezh (actually I think there's two words depending on whether they're made of buckwheat or ordinary flour)!

At least nobody's mentioned Muffin the Mule.
