Many years ago I saw, on Walt Disney, a story about a young boy and a grouchy old guy and a pigeon which said grouchy old guy was gonna cull but the young boy begged for its life and lo and behold it became a champeen racin' pigeon. He called the bird "Pidge". When I saw it written I understood why the "d" - I'd been thinking "pig" in my eight-year-old head, and saw it wouldn't have worked on paper. After all, pigs can't be champeen fliers, though apparently pidges can.

I have noticed in my reading that the "frig" spelling seems to be UK, and the "fridge" one North American.
So how do the English spell that boiled sugary candy? Fug? Oh, I can see it now.

"The fug's in the frig, dear."
